Any idea what this error log means?

[Kalina]

I created a custom SOP. Sometimes I can cook it successfully, other times it segfaults. It seems to always segfault after the "cookMySop()" function completes (i.e., outside of the code that I wrote???). When it segfaults, it either gives me one of two error logs, or no error log at all.

Here are the two error logs. Can anyone make sense of them and direct me in a direction that I can start to look to debug this?

posting this on the SESI forums would be your best bet - the SESI developers view those forums more often than these...

Thanks, will do.

Load Houdini with valgrind (I think it's mentioned in the HDK docs) with your test scene. Ignore all the messages it gives you except for the ones in your own code. Make sure you compile your plugin with the -g option so that debugging information is provided.

edward, thanks for the suggestion. I couldn't get valgrind working at first, but I just figured it out. I'll report back if I have more questions or relevant findings.
