Description Rodrigo Kumpera 2012-11-19 18:15:55 UTC
We disabled stack adjusment as a workaround for #2190. Master has this as a2765786db2947250afabcc2c108d1d081f82e83

We need to figure out a way to handle this properly.

This is now fixed by master, mono_find_jit_info () is now async safe is invoked in async context
(mono_thread_info_set_is_async_context ()), but the returned MonoJitInfo is missing some fields like MonoMethod etc., so callers need to be updated to work without this info if possible.

The current cases are as follows:
- The handler block guard code. This has been fixed in 9a6510ece63cee1a0416c123f8de84767b3ae2e2.
- sdb. This has been worked around by eagerly loading jit info for all AOT methods, so 
  mono_aot_find_jit_info () is never called in an async context.
- all the async signal handlers.

Fixed some time ago.
