Using gcc-3.4.1-20040517, building groff-1.19.1 with these CFLAGS: "-Os
-march=pentium4 -pipe" causes a sig 11 when the Makefile tries to produce pic.ps.

Using "-Os -march=pentium3 -pipe" does not cause this problem. The builds are
being done on a P4 2.6C with hyperthreading, running a current glibc snapshot
and the 2.6.6 Linux kernel.

Confirmed.

BTW, I also had to set CXXFLAGS to the value mentioned above.

It's actually the program "pic" located in "groff-1.19.1/src/preproc/pic"
that crashes. I'll add a minimal input file for the miscompiled "pic" that
triggers the segfault.

The culprit is in the function box_object::print() in object.cpp,
where the program crashes. Removing the following 4 lines from the
assembler code makes things work again (the lines are missing if
one compiles the code with -march=pentium3):

========================================================

I'll attach a short self-contained testcase to reproduce the function
box_object::print(). Just compile with "g++ -Os -march=pentium4".
(The assembler labels are of course different, but there are only
four lines that contain %xmm0.)

To actually run the code one has to build groff, though.
So this testcase is not completely self-contained,
but maybe this is enough to identify the bug.

This looks like a case where the stack pointer is misaligned, movaps requires 16byte (128bit) aligned 
addresses So this caused by -Os implying -mpreferred-stack-boundary=32 which is wrong for SSE.  
Maybe the fix would be to imply -mpreferred-stack-boundary=128 if -msse (or is it -msse2) is turned 
on with -Os, this also causes var_arg25.c (I think) to fail at -Os.

Jan I added you as CC to find your opinion  on my suggestion.  I think a huge amount of people will run 
into this if they used -Os without knowning what is going on.

gcc -Os -march=pentium4 -S testcase.cc
