Bugzilla Bug 147250

I'm getting a segmentation fault during build of qdvdauthor using gcc-4.1.1. 
My system has been upgraded and emerge -e world completed, with no success. 
Please see emerge --info below.  Thank you.

I attempted to emerge this same package on another machine and received the
same error, however after reviewing the build of qdvdauthor, I found another
error that may provide more information.  Still another segmentation fault.

same error here for version media-video/qdvdauthor-0.1.2 and
media-video/qdvdauthor-0.1.2-r1
(x86 pentium 4 with gcc-4.1.1)

since I'm able to compile all versions in portage w/o any problems with GCC
4.1.1 on different machines (Athlon-XP, P3, P4, etc.) I guess you haven't
upgraded your system correctly after the switch to GCC 4.1

trust me, recompile *everything* on your system and your problems are gone. I
know what I'm talking about. I also had serious problems after migration to GCC
4.x, when only a few libs were (re-)compiled with GCC 4.x and the rest was
still GCC 3.x.

ok, other possibility could be, that there is a bug in GCC 4.1.1, but then the
gcc-herd should be involved.

because of this message:
"internal compiler error: Segmentation fault"

all I can say is, that it compiles fine here on my machines. So I can't
reproduce it.

btw: CFLAGS="-O4 -march=pentium4 -pipe"

would you be so kind please and try "-O2" instead of "-O4".

Got the same segfault while upgrading my system to gcc 4.1.1.

I use CFLAGS="-march=athlon-xp -O3 -pipe -fomit-frame-pointer" on my pc.

After changing -O3 to -O2 qdvdauthor merged fine.

> After changing -O3 to -O2 qdvdauthor merged fine.

ok, looks to me, that we have to use 'filter-flags' and friends. ;-)
I will provide a fix.

ok, I fixed it in CVS. But no new release, it's still 0.1.2-r1.
Please test it. Thanks!

no response? So I guess it's fixed...

My apologies, I've had a few other issues with internet connectivity.  My poor
router went up in flames.  At any rate, after changing optimizations on the
compiler, this seems to have fixed the issue.
