Hi,
Fedya asked me to debug why rpm (and urpmi) were not working
on OpenMandriva arm after updating to gcc 4.9.
The backtrace looks like this:

Initially I asked Fedya to build a rpm with --disable-openmp, but after some
hours building it, it is still linked to libgomp, because beecrypt is linked
to it, so, next steps should be somewhat like testing if rpm can be built
without beecrypt, or if beecrypt can be built without openmp...
But rpm experts may know better about it...
Thanks,
Paulo
