This should be a different problem. From gfortran.dg/csqrt_2.f:
PR libgfortran/24313
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24313

This test checks for bug in glibc's csqrt and was marked xfail
*-*-linux-gnu.
Since the bug has been fixed in glibc (2005-10-13 and for cacosh
2006-08-03), the xfail has been removed (Oct 29, 2006).

If you have an older glibc, it passed before and gives now FAIL.
If you have a newer glibc, it XPASSed before and gives now PASS.

Knowing how often Debian releases a stable version, you probably have a
too old glibc.
