Fixed on 4.0.x according to:
http://gcc.gnu.org/ml/gcc-testresults/2005-10/msg00450.html

Also on 4.1 (when 4.1 bootstraps Ada):

No, I'm afraid not.  The situation is actually worse than before.
In both those test runs, I had to kill the acats testsuite because
it hangs.  The normal timeout doesn't occur.  Thus, we didn't get
to the cxg tests.

With gcc 3.4.2 (release) on hppa2.0w-hp-hpux11.11, the nature of the failure
has changed.  The ada testuite now hangs when cxg2014 is run.

...
BUILD cxg2014.adb
gnatmake --GCC="/xxx/gnu/gcc-3.3/objdir/gcc/xgcc -B/xxx/gnu/gcc-3.3/objdir/gcc/"
 -gnatws -I/xxx/gnu/gcc-3.3/objdir/gcc/testsuite/ada/acats/support cxg2014.adb -

gnatlink cxg2014.ali --GCC=/xxx/gnu/gcc-3.3/objdir/gcc/xgcc -B/xxx/gnu/gcc-3.3/o
bjdir/gcc/
RUN cxg2014

The hang occurs at exactly the same point as before.  Someday I'll try
and debug this further.

The cxg are not failing for a small amount given the log you gave,
and it looks like it concerns Long_Long_Float handling.
I suspect it might be general weakness in handling Long_Long_Float
on platforms where it's not the same as Long_Float, see ada/14988

There's potentially two separate issues involved in this PR
and 13528:

1) The float to integer conversion of an Inf which causes a
   SIGFPU and the termination of the acats test sequence.

   This is definitely a testsuite/ada problem.  I don't have
   a copy of the IEEE spec handy but the PA-RISC 2.0 Architecture
   book indicates that an unimplemented exception is always
   signaled for this condition.

2) The failure of various cxg* tests (and some others) due
   to the error limit for the test being exceeded by a small
   amount.

I suspect that the cxg* failures have been present on the hppa2.0w-hp-hpux11
port since the acats testsuite was installed.  This report represented
the first successful build of ada since the testsuite was installed.  I
could do a build just after the testsuite was installed to see if there
was any regression from that time.  I would have to backport Roger Sayle's
loop.c patch.  It resolved the miscompilation of gnat1 which prevented
builds for a long time.

The numeric failures don't occur on the hppa-linux port.  Thus, I doubt
the problem is directly in the GCC code.  The primary differences between
the two ports are:

a) HP libc/libm versus glibc
b) Long double on hppa-linux port is the same as double.  Long double
   on hppa-hpux port uses HP "quadlib" routines in libc.
c) Linux port has flat memory model and doesn't need to be built with
   -mdisable-indexing.

`c' usually results in segmentation faults, so I doubt it is the problem.
