Segmentation fault in embedded libgomp

[dalsh]

Hi,

I had an issue similar to #436 after packaging my app, which was running fine on windows, into a docker image.

The Unsatisfied link error is now resolved but I am now encountering the following segmentation fault when running my app :

#
# A fatal error has been detected by the Java Runtime Environment:

What I've done is replace my javacv:1.2 by javacv-platform:1.3.2 in my pom. I'm building and running everything using the same jdk (docker image maven:3.5-jdk-8-alpine) I'm probably missing something here, please tell me if I can provide any more information

Try to use the libgomp.so that comes with your distro instead of the one bundled.

Thank you for your answer. We have switched from alpine to debian and it is now working.

Ah yes, the Alpine build of OpenJDK is known to be quite buggy.
