------- Comment #12 from jakub at gcc dot gnu dot org 2010-06-12 19:29 ------- Instead of spending too much time on testsuite reduction, perhaps if you could put a breakpoint on builtin_define_with_hex_fp_value where lazy_hex_fp_values[XXX].macro is initialized (for XXX being the idx which crashes later on), see the content of what it points to and its tokens, then put a breakpoint on lazy_hex_fp_value and see what it contains at that point, if it changed (it shouldn't), rerun and put a watchpoint on whatever actually changed in between the two to see where it gets clobbered and why.
