Also this command sequence doesn't give me a crash. However I added the patch, which fixes the issue on your end, you mentioned in a different mail on the patch series and ran a make check with and without the patch. No regressions detected on my system. I've pushed the new series to Github: https://github.com/intel-gdb/vla/tree/vla-fortran Could you please give it a try? > > Thanks, > Jan > Thanks, Keven
