[Bug fortran/33174] New: Testsuite: unexpected failures

[dir at lanl dot gov]

Some of my programs run Ok with gfortran on the Macintosh and Linux, but fail
on CYGWIN and MSYS - so I ran the testsuite. Several unexpected failures were
found -

cygwin or msys? What is the host, what is the target?

As far as I see, there is only one gfortran failure:

FAIL: gfortran.fortran-torture/compile/pr32417.f90,  "-O"   (internal compiler
error)

I don't see it on a fresh mingw native compiler (rev 127394M).

The Host and the Target was cygwin. There 60 unexpected failures in the gcc
testsuite and one in the fortran testsuite. 

I have the latest version of gcc (3.4.4) that the cygwin site gives out. Is
that the "fresh mingw native compiler" ?

The gcc and gfortran are version 4.3.0 20070723 from svn, built on the cygwin
system.

[Bug fortran/33174] Testsuite: unexpected failures

[fxcoudert at gcc dot gnu dot org]

------- Comment #6 from fxcoudert at gcc dot gnu dot org  2007-08-27 10:10 -------
So everything (target == host) is cygwin. I'm sorry for the confusion, but as
you talked about MSYS in your original report, I thought it would be some kind
of cygwin-hosted mingw compiler...

About the failures themselves:
  * it is currently expected that
gfortran.fortran-torture/execute/intrinsic_integer.f90 fails, because of a bug
in the cygwin math library; I'm surprised that it doesn't fail for you
  * could you try to compile pr32417.f90 yourself, and produce a backtrace of
the ICE? Use "gfortran -v pr32417.f90", from the output of that command, look
at the command-line for the "f951" command, run it under gdb (gdb -args
/path/to/f951 .....), set a breakpoint on fancy_abort ("break fancy_abort") and
when the breakpoint (or a segfault) is hit, ask for backtrace ("backtrace").
Copy-paste the result here.

My programs fail in the save way on MSYS and GYGWIN, but on none of the other
versions of gfortran. 

I tried intrinsic_integer.f90 by hand and it does not fail on my gfortran
version.

Here is the traceback for pr32417.f90 -

That ICE is most likely PR 33140.

PR 33140 disappeared from mainline around 2007-09-08. Dale, can you still see
the ICE you reported?

I have tried twice, but I cannot get the testsuite to work. After I added
"--enable-checking", The "make -k check-fortran" does a little and fails with -

ERROR:runtest.exe does not exit.

I not sure what is happening - it was working.

Hi Dale,

pr32417.f90 doesn't ICE any more, closing this PR. Please reopen if you have
more information.
