I am rather new to Gentoo, but I have been able to make almost all
software and hardware work, except for one program: Xpdf... When I try
to open a pdf-file with Xpdf I get the error: Segmentation fault. - I
have tested my memory with memtest86, and the memory is OK. I cannot
find any debug commands for Xpdf. - Any help will be appreciated...

What happens if you don't try to open any file and just start xpdf?

Then it starts up without any problems.

When I try to open a pdf-file it terminates with "Segmentation fault"...

Good.

Any PDF file? How many have you tried? Did you try different PDF files
from different sources?

Also, try running 'revdep-rebuild' as root.

I have tried perhaps 10-12 different files. - Some of them are from
different sources.

The output from the 'revdep-rebuild'-command is:

Ok. Have you tried re-emerging xpdf? Searched the gentoo forums for
'xpdf segmentation fault' or 'xpdf segfault'?

Alternatively, you could re-emerge with the 'debug' flag, and use gdb
to figure out where exactly things are going wrong.

I have reemerged xpdf twice. I have however not installed gdb yet, I
will try that...

I too am rather new to Gentoo, but I wonder if "strace" might
help to diagnose the problem:

http://hegel.ittc.ukans.edu/topics/l.../strace.1.html

"Emerge <args> dev-util/strace"

R.

Now I have tried gdb. The output from gdb is:

Starting program: /usr/bin/xpdf
warning: Unable to find dynamic linker breakpoint function.
GDB will be unable to debug shared library initializers
and track explicitly loaded dynamic code.
warning: shared library handler failed to enable breakpoint

Program received signal SIGSEGV, Segmentation fault.
0x40573513 in ?? ()

I'm afraid it does not tell me a lot...

When i write (as ordinary user) 'strace xpdf' there is a lot of
messages, but as far as I can se the most important is in the end:
