           Summary: gcc 3.3.1 with -Os flag once again builds QT library
                    incorrectly
           Product: gcc
           Version: 3.3.1
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: t dot artem at mailcity dot com
                CC: gcc-bugs at gcc dot gnu dot org

My system: Linux RedHat 9.0
GCC version: 3.3.1 vanilla with no 3d party patches applied
Application I tried to compile: QT library 3.2 (www.trolltech.com)

Issue: I changed the compilation flag of QT library found in mkspecs/g++-
linux/...
The default was "-O2" I put "-Os -march=pentium2".
Hint: I'm building multithreaded QT libary
The problem: After building libqt-mt.so and building uic (a part of QT suit) 
application, uic itself segfaults almost after _every_ _second_ time I try to 
use it to build other QT based applications (uic means user interface 
compiler). Actually it does its work but then after munmap it produces segfault.

I encountered this problem with _all_ gcc 3.x.x (version < 3.3) versions 
_except_ gcc 3.3. It works perfectly with this (-Os) flag. So I decided to stay 
with 3.3 release

Does it segfault when you build with -g -Os as well? If not, can you find out (via gdb) where uic is 
segfaulting? That might help localize the problem at least.
