Artur reports: GUI unit test executable crashes at the end of compilation. System affected: PSI Linux cluster with manual installation of packages here and there.

Normally such kind of behavior can be connected with older BornAgain installation in the LD_LIBRARY_PATH or older libgoogltest.so installed on the system.
This is not the case here.

Bug in Qt?

  • Status changed from Sprint to Resolved

Bug was connected with

namespace {
const QString x = another;

Where `another` was static QString initialized in another module.

I.e. the error was connected with undefined order of QString initialization.
