strace output of rpmbuild when it works

When it crashes, the log ends with the following:

open("/usr/lib/rpm/rpmpopt-4.3.1", O_RDONLY|O_LARGEFILE) = 3

When it doesn't crash, the log contains:

As you can see: it crashes just before the line:
open("/etc/rpm/platform", O_RDONLY|O_LARGEFILE) = 3

When i use gdb, i get the following backtrace:

As suggested by nasrat on #rpm, i also tried with i386-redhat-linux in
/etc/rpm/platform but the same problem remains.

As suggested by jbj on #rpm, a check of the contents of the file
/etc/rpm/platform:
od -c /etc/rpm/platform
0000000   i   6   8   6   -   r   e   d   h   a   t   -   l   i   n   u
0000020   x  \n
0000022

I also tryed with valgrind as suggested by jbj but i only get
'segmentation fault' as output, but that's probably because i've no
idea how to get valgrind to give me usefull output :-)

buildlog of rpm which i compiled and installed and which works without problems

I've downloaded and installed the source rpm of rpm-4.3.1-0.3. I only changed
the Release in the spec file so rpm -Uvh is easy. After a build, i installed it
and now rpmbuild works without any problems.

THis problem appears unique to your machine and so I am going to close.

Please reopen if the problem reappears.
