[Mono-dev] PPC create domain

[Joachim Ante]

Hi, (Sorry last mail was sent off too early)

I am having a bit of trouble getting domain creation under control on PPC
machines.

Very rarely i am getting this error:

** ERROR **: file mini-ppc.c: line 2329 (handle_thunk): assertion failed:
(pdata.found == 1)
aborting...

=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

Another issue is we are sometimes running multiple instances of embedded
Mono shared libraries. (They are in a different dylib file thus completely
seperate)

I have a reproducable bug (But of course only in our web player and a test
case with just mono) where I load one mono dylib, create a domain in it,
then load the other mono dylib, create a new domain there, when calling
ExecuteAssembly i get a SIGILL exception.

   System.ExecutionEngineException: SIGILL
  at <0x00000> <unknown method>

  at (wrapper remoting-invoke-with-check) System.AppDomain:ExecuteAssembly

  at UnityEngine.UnityDomainLoad.CreateDomain () [0x00000]



Are there any known issues with domains on ppc? Does anyone have an idea why
it would be bad to load mono twice in the same process? (from seperate
dylibs)

Sorry this is not very informative, i am just pretty lost about what is
going. Just want to hear if someone can give me a hint.

Best regards,
