Internal compiler error in 4.1.0

[<michael dot miller at prga dot com>]

Trying to build crosstool 0.42 for arm xscale using gcc 4.1.0 and glibc
2.3.6.  Base system is Mandriva 2006 on an Intel box with gcc 3.4.5:

-Wall -Winline -Wstrict-prototypes -Wwrite-strings   -fPIC

../sysdeps/generic/s_fmax.c: In function `__fmax':

../sysdeps/generic/s_fmax.c:28: internal compiler error: in
elim_reg_cond, at flow.c:3328

 

This is in the 2.3.5 math library portion.  Seems like this is similar
to an old bug PR15068 but I haven't looked into in detail.
