------- Comment #8 from sje at cup dot hp dot com 2009-02-05 20:41 -------
My IA64 HP-UX bootstrap worked but my IA64 Linux bootstrap failed. When
building libgfortran the configure script tried to compile:
| program foo
| real, parameter :: bar = sin (12.34 / 2.5)
| end program foo
and the Fortran compiler gave a seg fault.

Ack, my HP-UX and Linux builds were from two different source trees. The HP-UX
build that worked had the patch, the Linux build that failed did not have the
patch applied.
