it seems it's either a compiler bug or a XEmacs bug triggered by the
new compiler --- I've just verified that a new version og gcc was made
available in the unstable repository, so in a few minutes I'll let you
know something more
not a few minutes, anyway...

I configured and built XEmacs with the above gcc and it still fails

I tried gcc 4.9.0 with not problems. 4.7.3 works fine to.
On the other hand I could not use the exact same configuration. To
many packages that I don't have installed. So I had to remove some
'--with...' to get a build.
I also use make check as a test. With 100% success on the mule test
that would indicate that I could not reproduce it right?
I also tried to use the manual steps with loading test-harness etc but
then I get an error that Assert isn't known. I guess you get the
crasch before that so that is also an indication I cant reproduces it.

Yeah, I have a 4.8.1 build on Mac OS X now, tests run to completion
with no failures in mule-tests.
On the other hand I could not use the exact same configuration.
If the compiler is unbroken, this test should not be affected by build
options.
I also use make check as a test. With 100% success on the mule test
that would indicate that I could not reproduce it right?
Correct.
I also tried to use the manual steps with loading test-harness etc
but

No, Assert gets defined very early in the process. No Assert, no
tests.

The procedure I was referring to was this below, stated earlier in
this thread:
----------------------------------------------------------------------
i started src/xemacs
i load-library test-harness
i find-file tests/automated/mule-tests.el
in the buffer with mule-tests
i required bytecomp
i eval-last-sexp on (defun test-chars ...)
i eval-last-sexp on (test-chars )
----------------------------------------------------------------------
As I get it the Assert macro is not defined just by loading
test-harness so when evaling (test-chars ...), in the context given
above, it is unknown.

this thread:
Yeah, Assert is a macro gets defined by the functions that run tests,
like test-emacs-test-file. Then when they're done, it gets undefined.
To find out about what functions you can use just by loading
test-harness, you'll have to read the file (test-harness.el), it's not
well documented.
There may be more information in the Internals manual.
But I'm pretty sure that this is something special to Giacomo's
platform. We just got another "this can't happen" report, so I'm
suspecting there's a bad patch floating around the distros. Dunno
whether it's to XEmacs or to GCC, but if that's what it is, I'd guess
it's to GCC.

So it seems. Given that we can't recreate it there is little we can do
at the moment. If there comes up some new idea of what to test I'll be
happy to assist.
