I put up a MonoTouch class library project for Microsoft Reactive Extensions here: https://github.com/stampsy/rx-monotouch When I build an app that references it, in Release mode, I get this error: AOT Compilation exited with code 134, command: MONO_PATH=/Users/dan/Documents/Projects/<Redacted>/bin/iPhone/Release/<Redacted>.app /Developer/MonoTouch/usr/bin/arm-darwin-mono-sgen --llvm --aot=mtriple=armv7-darwin,ntrampolines=2048,nimt-trampolines=512,full,static,asmonly,direct-icalls,nodebug,llvm-path=/Developer/MonoTouch/LLVM/bin/,outfile=/var/folders/85/sx0_jgqj10q63hc5fn32v2rh0000gp/T/tmp3f97d2fd.tmp/System.Reactive.dll.armv7.s "/Users/dan/Documents/Projects/<Redacted>/bin/iPhone/Release/<Redacted>.app/System.Reactive.dll" Mono Ahead of Time compiler - compiling assembly /Users/dan/Documents/Projects/<Redacted>/bin/iPhone/Release/<Redacted>.app/System.Reactive.dll * Assertion at ../../../../../mono/mono/mini/mini-arm.c:4011, condition `arm_is_imm12 (ins->inst_offset)' not met It builds for Simulator just fine.

The simulator uses the JIT (not the AOT). Did you try it under different conditions ? E.g. does it happens when you do not use LLVM (which is a different AOT compiler backend) ?
I tried turning off LLVM, choosing Don't Link and adding -nosymbolstrip. None helped.
This is an ARM JIT bug.
Fixed in master/mobile-master.
Hi folks, thanks for fixing this one. When can we expect this to land in production, at least in Beta? We're releasing our app in the end of January and ideally we would love to use this fix.
As a workaround, you can try removing unused virtual methods from the System.Reactive.Linq/Reactive/Linq/QueryLanguage.<..> files.
Will give it a try. Thanks.
If anyone is curious, I fixed the compilation by adding NO_LARGEARITY to compiler constants. Probably this was killing the compiler: #if !NO_LARGEARITY Func<T1, T2, T3, IObservable<TResult>> FromAsyncPattern<T1, T2, T3, TResult>(Func<T1, T2, T3, AsyncCallback, object, IAsyncResult> begin, Func<IAsyncResult, TResult> end); Func<T1, T2, T3, T4, IObservable<TResult>> FromAsyncPattern<T1, T2, T3, T4, TResult>(Func<T1, T2, T3, T4, AsyncCallback, object, IAsyncResult> begin, Func<IAsyncResult, TResult> end); Func<T1, T2, T3, T4, T5, IObservable<TResult>> FromAsyncPattern<T1, T2, T3, T4, T5, TResult>(Func<T1, T2, T3, T4, T5, AsyncCallback, object, IAsyncResult> begin, Func<IAsyncResult, TResult> end); Func<T1, T2, T3, T4, T5, T6, IObservable<TResult>> FromAsyncPattern<T1, T2, T3, T4, T5, T6, TResult>(Func<T1, T2, T3, T4, T5, T6, AsyncCallback, object, IAsyncResult> begin, Func<IAsyncResult, TResult> end); Func<T1, T2, T3, T4, T5, T6, T7, IObservable<TResult>> FromAsyncPattern<T1, T2, T3, T4, T5, T6, T7, TResult>(Func<T1, T2, T3, T4, T5, T6, T7, AsyncCallback, object, IAsyncResult> begin, Func<IAsyncResult, TResult> end); Func<T1, T2, T3, T4, T5, T6, T7, T8, IObservable<TResult>> FromAsyncPattern<T1, T2, T3, T4, T5, T6, T7, T8, TResult>(Func<T1, T2, T3, T4, T5, T6, T7, T8, AsyncCallback, object, IAsyncResult> begin, Func<IAsyncResult, TResult> end); Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, IObservable<TResult>> FromAsyncPattern<T1, T2, T3, T4, T5, T6, T7, T8, T9, TResult>(Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, AsyncCallback, object, IAsyncResult> begin, Func<IAsyncResult, TResult> end); Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, IObservable<TResult>> FromAsyncPattern<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, TResult>(Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, AsyncCallback, object, IAsyncResult> begin, Func<IAsyncResult, TResult> end); Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, IObservable<TResult>> FromAsyncPattern<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, TResult>(Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, AsyncCallback, object, IAsyncResult> begin, Func<IAsyncResult, TResult> end); Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, IObservable<TResult>> FromAsyncPattern<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, TResult>(Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, AsyncCallback, object, IAsyncResult> begin, Func<IAsyncResult, TResult> end); Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, IObservable<TResult>> FromAsyncPattern<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, TResult>(Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, AsyncCallback, object, IAsyncResult> begin, Func<IAsyncResult, TResult> end); Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, IObservable<TResult>> FromAsyncPattern<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, TResult>(Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, AsyncCallback, object, IAsyncResult> begin, Func<IAsyncResult, TResult> end); #endif
