[Mono-dev] News about Bug 623477

[Rodrigo Kumpera]

Well, the most appropriate behavior would be to expose a new runtime
function
that returns the smallest allowed stack size.

Something like:

--in metadata/theads.c

int
mono_thread_get_stack_min_size ()
{
#if defined (PTHREAD_STACK_MIN)
   return PTHREAD_STACK_MIN;
#else /*FIXME add more cases. Not sure WINAPI exposes such a thing*/
  return mono_pagesize (); /*A sane default*/
#endif
}


Then export it in icalls-def.h to a System.Threading.Thread static method.


And finally use this on managed code to properly check for minimum size.
Such change would be the appropriate way to go.

Torrelo, can you cook up such a patch? Either post it on bugzilla or make a
pull request.

Thanks,
Rodrigo
