Description Paul Seabury 2012-07-10 16:04:00 UTC
If I enable LLVM in my release build, I get the following Assertion failure and subsequent build failure (mtouch exited with code 1):

AOT Compilation exited with code 134, command:
MONO_PATH=/Users/pseabury/Projects/SO_11385906/SO_11385906/bin/iPhone/Release/SO_11385906.app /Developer/MonoTouch/usr/bin/arm-darwin-mono --llvm --aot=mtriple=armv6-darwin,full,static,asmonly,nodebug,llvm-path=/Developer/MonoTouch/LLVM/bin/,outfile=/var/folders/mt/b7h3_pgs3lxgpvpm2h1_2ppc0000gn/T/tmp3f6bfe89.tmp/ServiceStack.Text.MonoTouch.dll.6.s "/Users/pseabury/Projects/SO_11385906/SO_11385906/bin/iPhone/Release/SO_11385906.app/ServiceStack.Text.MonoTouch.dll"
Mono Ahead of Time compiler - compiling assembly /Users/pseabury/Projects/SO_11385906/SO_11385906/bin/iPhone/Release/SO_11385906.app/ServiceStack.Text.MonoTouch.dll
* Assertion at ../../../../../mono/mono/mini/mini-llvm.c:4535, condition `LLVMTypeOf (values [sreg1]) == LLVMTypeOf (values [phi->dreg])' not met

Self-contained test case attached. The sample code links to latest ServiceStack binaries, but if it makes debugging easier you can just use the main branch source for both ServiceStack & ServiceStack.Text.

Zoltan, this looks like your area.
Comment 3 Zoltan Varga 2012-07-16 21:20:39 UTC
Can't reproduce this using master.
Comment 4 Rolf Bjarne Kvinge [MSFT] 2012-07-17 06:53:41 UTC
I can confirm this is fixed in master (i.e. 5.3.5 when it is released), and it crashes with 5.2.
