VCS core dump

[GordonMcGregor]

Trying in a different environment (Python 2.7.1 that appears to be statically linked only - no libpython2.7.so just libpython.2.7.a

and a recent version of VCS ( Compiler version G-2012.09-SP1-3_Full64; Runtime version G-2012.09-SP1-3_Full64; Jul 9 14:08 2013 )

Any thoughts on the cause of the Interpreter not initialized error. Seen this before at all?

Compiler version G-2012.09-SP1-3_Full64; Runtime version G-2012.09-SP1-3_Full64;  Jul  9 14:08 2013
Fatal Python error: Interpreter not initialized (version mismatch?)

An unexpected termination has occurred in simv

During a VPI callback function for callback reason="cbStartOfSimulation"
Command line: simv +acc+1

It's not something that we have seen yet. Realise that is not much help.
Will have a think.

I worked around for now. (By switching to DPI launch, rather than VPI)

Gordon, I'm having trouble getting a stack trace from G2012.09 with the same options that give a trace on F-2011.12-SP1. Can you paste the command you used to get the trace for this issue?

[GordonMcGregor]

I think I ended up tracing this down to a mixup in python path and linked library - a peculiarity of the installed version here and how it is wrapped up, so the error actually makes sense:

Fatal Python error: Interpreter not initialized (version mismatch?)

[GordonMcGregor]
