Subject: [Bug middle-end/48377] [4.6 regression] miscompilation at -O3
Date: Tue, 05 Apr 2011 20:39:00 -0000	[thread overview]
Message-ID: <bug-48377-4-tFWDEfKul6@http.gcc.gnu.org/bugzilla/> (raw)
In-Reply-To: <bug-48377-4@http.gcc.gnu.org/bugzilla/>

--- Comment #6 from Matt Hargett <matt at use dot net> 2011-04-05 20:38:41 UTC ---
in the 46bug/ dir in the attached tarball:
g++ -O3 -g -I. -c te_field_id.cpp && g++ *.o -o test

induces the crash:

==31412==  General Protection Fault
==31412==    at 0x400F38: TE_Field_id::Initialize_token_maps()
(hashmap.hpp:710)
==31412==    by 0x4017A8: main (te_main.cpp:5)


This is the same crash I described before. Compiling with -O2 eliminates the
crash. In te_field_id.hpp, there is a commented out
__attribute__((optimize(2))). In the non-reduced case, adding that annotation
just moves the crash around. I may file a separate bug for that, depending on
the outcome of this bug.
