Bug #: 50239
Summary: compiled program segfault when -O0 is used to compile
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: eviom@mail.ru
Original thread:
https://bugs.launchpad.net/ubuntu/+source/gcc-defaults/+bug/591819
When I compile my code, if I compile it -O2, it compiles and runs fine. if I
compile it with -O0, it segfaults while rendering text with FTGL. I've made no
changes to anything in between compiles. Same FTGL code works fine in win32
(vs2010).

When I compile my code, if I compile it -O2, it compiles and runs fine. if I
compile the code without it, my program segfaults while rendering text with
FTGL. I've made no changes to anything in between compiles. Same FTGL code
works fine in win32 (vs2010).

There's no need to repeat the same info you already provided, please provide
what you _didn't_ provide, as requested by http://gcc.gnu.org/bugs/#report
we need preprocessed source, and preferably a minimal testcase that has been
reduced to the smallest example that still shows the problem
