Currently at 13hrs on an AMD Athlon 64 X2 5000+. It's using 1 core to the max and almost no memory (0.7% of 2G)
Works fine from FreeBSD w/ gcc 4.2.1.
Probably this upstream gcc bug http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36439
I just played some more and found out the following: If I switch from gcc-4.3.1 to gcc-3.4.6, it compiles on the machine I already posted (see comment #1). However, on my laptop (Core2Duo, mostly amd64 stable [see http://www.oliver-putz.de/bugreports/bug237839-Laptop-Working.txt]), it also compiles fine with gcc-4.3.1
@Petteri Räty: Hm, looks indeed very likely. My Laptop indeed uses -Os instead of -O2. Furthermore, if I change the optimizations to -O1, I can also compile it with gcc-4.3.1 on the computer that failes to compile it with -O2. Thanks for the hint!
Has anybody tried -O2 -fno-tree-pre to confirm it's actually _that_ GCC bug?
With "-fno-tree-pre" in CFLAGS, it still fails to compile. With MAKEOPTS="-j5" it stopped at where.c, with MAKEOPTS="-j1" it stopped at malloc.c, but the story's the same, it just sits there. A little further investigation seems to suggest it's the presence of "-ggdb" that's causing the issues. Without that present, it compiles fine, with that present, it hangs. Looking through this bug, all the other emerge --infos report "-ggdb" being present...
So we're hitting a different bug than the one from the one reported in GCC bugzilla, or #224611.
It compiles fine after upgrading gcc from 4.3.1-r1 to 4.3.2. Not sure if the same gcc bug or not as referenced, but it does succeed with compilation now.
Switching to gcc 4.3.2 fixes the build hang, too.
(In reply to comment #11) > Switching to gcc 4.3.2 fixes the build hang, too. > Let's say this is fixed then.
