However, 4.9.0+ works fine, as well as all active branches. Thus closing as resolved. |
Created attachment 30392 [details] File to reproduce bug Compilation of debug-1.c file from ./libgomp/testsuite with the following options: -g -fopenmp -O0 -gdwarf-2 -femit-struct-debug-reduced - causes segfault in the compiler. The described bug is actual for GCC versions 4.4, 4.6, 4.7. Works for -femit-struct-debug-reduced and -femit-struct-debug-baseonly I've attached both problem example and preprocessed file to the report.
