I realize the bug is not present in 7.4, but I am using 7.2.2 in a production system and this is messing things up. Is there any chance the fix for this bug could be backported to 7.2.2?

Further info: the attached file seems pretty minimal in producing this bug. For example, if using up to 8-tuples, the bug is not present; it is present if 9-tuples and 10-tuples are used. The -O option is necessary; neither -O0 nor -O2 produces the bug. ",bug,closed,normal,7.4.1,Compiler,7.2.2,fixed,,,Linux,x86_64 (amd64),Compile-time crash,Unknown,,,,
