Broken ('bad') test program

... forget the comment about the 'lis' + 'stw' commands; I looked into the
wrong binary ('personality')...

For completeness (I do not know, how long the buildlogs are kept) the
visible problem:

| + gdb --batch --command=/builddir/build/SOURCES/personality.gdb ./lib/testsuite/cflags

RPM build errors:
    Bad exit status from /home/byte/rpm/tmp/rpm-tmp.49720 (%build)
make: *** [ppc] Error 1

Is this another error? 

If I run a make check on the package contents in FC-4, it exits w/o error.

comment #4 is due to another error (dunno, why it happens with the ppc compiler
only but not with the i386 one).

The 'make check' errors are caused by a kernel bug in the ELF loader.

Your 'cflags-bad' test program seems to work fine on current kernels. Please retest.

Just mail me a SSH public key.

Is this what is blocking a build of this package in devel to fix the broken
upgrade path? 

    util-vserver
      FE5 > FE7 (0:0.30.212-1.fc5 > 0:0.30.211-1.fc6)
      FE6 > FE7 (0:0.30.212-3.fc6 > 0:0.30.211-1.fc6)

I just did a mock build here on my ppc test box and it worked fine. 
Could you try pushing another build out to fix the E-V-R issue?
