Could you run the test without the output redirection and post the output
to tst-cancelx4.out, so we can see the exact point at which it segfaults?

Sorry, that was mangled. Could you run the test without the output
redirection to tst-cancelx4.out and post the output? (The contents of
tst-cancelx4.out *might* be helpful, but running without redirection may
avoid issues with stdio buffering and so make it more likely that the
point at which the output ends is actually the point at which the test
crashed.)

Running the test with --direct will skip the fork.

You need to run it via testrun.sh to pick up the uninstalled library from the
build directory.

If there are references like that to system libraries, the test is not
being built or run correctly. Either run it with the exact (very long)
command, including environment settings, that the testsuite itself uses,
or else rebuild the test with -Wl,-dynamic-linker and -Wl,-rpath options
pointing to the appropriate places in the install_root directory you
specified when installing the newly built library.

Better backtracing is certainly one reason to rebuild the test with
appropriate -dynamic-linker and -rpath options (given that you've
installed the library somewhere) so that it can be run directly rather
than via the dynamic linker.

This is tricky. It could be a miscompilation of either glibc or the testcase by
the compiler which causes the unwinder to fail.
When you run the testsuite for glibc what are the results?
The official 2.16 release had a clean testsuite run:
http://sourceware.org/glibc/wiki/Release/2.16
The reason I ask is that other failures in the testsuite might indicate a
problem with your build environment.

You are applying Gentoo specific patches to glibc, and that makes it difficult
for us to help you. If you were doing a vanilla glibc build, and your test
results were clean with the exception of tst-cancelx4, then we could help. As
it stands you have over 45 errors with the testsuite. Something is wrong with
either your compiler, linker, assembler, or dependent libraries.
The best thing you can do now is to go back to Gentoo and seek help with their
maintainers to determine why you have so many failures building glibc for that
distribution.
We aren't gentoo experts and we don't know or understand the patches you are
applying. Given that I'm closing this issue as resolved and invalid, not
because we don't want to help, but because we don't have the required
experience to help you. If you are building a modified glibc in gentoo please
seek help with gentoo first and work on reducing your testsuite failures.
