DetailsDescription:
the waitkey triggers sigfpe sometimes in 3.4.2-1, but does not in 3.4.1-3 Additional info: * package version(s) * config and/or log files etc. Steps to reproduce: build the attached qtproject with release/profile mode P.S. I think it's the -O2 option that matters, not tried to compile with g++ directly though
