------- Comment #1 from tbm at cyrius dot com 2007-01-23 17:51 -------
My backtrace looks slightly different but I can confirm this bug for
arm-linux-gnueabi. Lennert Buytenhek reported on debian-arm that fortran fails
to bootstrap when building natively and I verified that the testcase also
segfaults for me - both with current GCC 4.1 and 4.2 from SVN.
Program received signal SIGSEGV, Segmentation fault.
