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.
