[gentoo-user] can't compile some C++ apps

[Daniel Vrcic]

Hi list!

I have some strange problems with compilation of C++ apps. I've done
numerous emerges today and it turns out that _only_ compilation of
some C++ applications fail(?!). I get always the same error message:
"internal compiler error: Segmentation fault". For example avidemux has
some part of source written in C++. While compilation of .c part goes
very well it suddenly breaks with compiling .cpp file (some of .cpp
files actually pass) and emerge spits out:

---------
   ADM_vorbis::run(uint8_t*, unsigned int, uint8_t*, uint32_t*)':
audiocodec_ogg.cpp:187: internal compiler error: Segmentation fault
---------

I get the similar error with wxGTK, kdelibs, libvisual-plugins and few
others, but not with filelight for example(see below).

 wxGTK

I have also successfully compiled some C applications today and none of
them teased me as C++ ones had.

+ three manual kernel compilations.

I have three RAM modules and memtest86+ doesn't report any error on
either of them. I also don't experience any sudden application crashes
(except emerging :) ).

The only significant thing I've done recently and think it's worth of

Please, can someone shed up some light on this.

Segfaults compiling are almost always a hardware issue. memtest86 is
just about useless today, as it cannot detect problems due to dma or
memory timings.

Try the memtest script available at:

http://people.redhat.com/dledford/memtest.html

The other thing I would try is to take out the -mmmx, -msse2, and
-mfpmath=sse flags.  They will be enabled for those ebuilds where it
is safe to do so by the USE flags.

I ran it twice yesterday and it didn't print anything on stdout which
means that those tests passed.

I've also run it today with NR_PASSES=10:

[36] % ./memtest.sh
./memtest.sh  288.38s user 441.55s system 9% cpu 2:01:45.25 total

Doh, I forgot to say in the original post that I've already tried
removing those flags, but that, unfortunately, didn't help. :(

I'm still not able to compile the newest avidemux, k3b, kpdf, amarok...

Isn't that strange that _all_ C compiles (including some bigger apps
like kernel, mplayer, glib, gtk+) went fine apart from only few C++'s
(I think two)? If I have a hardware issue, how come that compilation of
those programs always break, and always on the same file and line of
certain source?

Please, any more tips, advices?

Maybe because c++ compilation eats loads of memory and thus hits the 
fishy parts?

Maybe a broken compiler.  Try recompiling your toolchain (binutils, 
glibc, gcc) without the funny stuff in the CFLAGS, twice.  Then try 
compiling the failing packages again.

> Please, any more tips, advices?

Pull out two of the RAM modules and use only one, trying each of 
them in turn.  Make sure you have enough swap (500 MB will do).  
Maybe all modules are individually okay but can't work together.

Stupid question, but how do I unsubscribe from this list?

Hmm, seems that that helped. I didn't change CFLAGS, instead I kept the
original. Hey, I was afraid of compiling gcc and glibc with "broken"
compiler until today. ;)

Thanks Benno!
