where is FFIErrorCallFrameTooBig being signaled?

 
Hello,
in my attempts to use OpenGL with the cog linux vm (4.0-2522, with or without mt) I get an error 'Call requires more
than 16k of stack space' on a number of pretty innocent calls. I found where the constant for this error is defined
(FFIErrorCallFrameTooBig) but I did not find where this error is being detected.
I currently do not have a working VMBuilder environment, so I've been using the Monticello snapshot browser to look at
the FFIPlugin sources in various VMMaker versions, but I could not find it anywhere.
Can anybody point me to the right spot?

Thanks,
Hans-Martin

Ok, found it. Just need to use the right tools (load the complete sources.st from the .mcz file into a workspace and
search...).
Now trying to find out why my calls could raise this error.

Cheers,

It's actually an incompatibility between the threaded FFI and the OpenGL extension function loading mechanism.

Thanks HMM!!
