segfault in external library in batch mode (not in GUI mode)

[joelo]

Hi

Im writing a plugin deriving from rendersettings.
It basically uses openimageio to do some custom writing to an exr file
creating and opening the file in framebegin and writing to it and closing it in frame end.
When in ui mode everything is working right, but when in batch mode
i get a segfault in Imf::header destructor
.
The files are written correctly in both scenarios.
Is there a difference in what objects are available in batch mode and
ui mode or some call order that is different?

I don't think so. If you are on Linux, make sure to hide all symbols you can, since they can cause such crashes.

Thanks

It was a version mismatch in the external library. It works now

Ok, great!
