segmentation fault at finalize

[norihiro-w]

Hi,

I've installed deal.ii v9.4.2 using candi on Ubuntu. The installation finished successfuly. However, running the examples (both step-1 and step-2) ended with segmentation fault.

Below is output of backtrace. It looks the executables mostly worked but crashed at finalization stage and the crash is somehow related to opencascade.

A temporal workarond is disabling opencascade in candi build.
