Segmentation fault in libVSC.so when linking shader

Frbale — Tue, 19 Oct 2021 21:26:39 GMT

We have a graphical application that segfaults in /usr/lib/libVSC.so. seemingly when linking shaders. Are there any hints at what could be the reason?

Partial backtrace:

Hello Frble,

Can you tell us which processor are you using? in any special case do you received this segmentation fault? please send us a test reproducible code.
