[Vm-dev] where is FFIErrorCallFrameTooBig being signaled?

[Hans-Martin Mosner]

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
