------- Additional Comments From Tobias dot Schlueter at physik dot uni-muenchen dot de 2004-04-20 21:42 -------
Changing the third line to
INTEGER, POINTER :: P ! no initialization
seemingly exposes memory corruption inside the compiler:
[tobi@marktplatz src]$ gcc/build/gcc/f951 t2.f90
a
Execution times (seconds)
final : 0.00 ( 0%) usr 0.00 ( 0%) sys 0.01 (12%) wall
TOTAL : 0.03 0.00 0.08
Extra diagnostic checks enabled; compiler may run slowly.
Configure with --disable-checking to disable checks.
[tobi@marktplatz src]$ gcc/build/gcc/f951 < t2.f90
Warning: Reading file as free form

a
f951: internal compiler error: Segmentation fault
Please submit a full bug report,

See <URL:http://gcc.gnu.org/bugs.html> for instructions.
[tobi@marktplatz src]$
i.e. only when reading from stdin the compiler segfaults. I'll attach valgrind
output for both cases.

Note you cannot just attach with valgrind as the GC in GCC will throw it off, you can use --enable-
checking=valgrind to enabled the use of valgrind.

Ok, will try that way tomorrow.
If you look at the output I attached, it still looks like valgrind didn't
generate random information: annotate_with_file_line() will have a hard time,
when the input file is stdin.

Ok, I built with --enable-checking=valgrind and ran 'valgrind f951 t2.f90' and
'valgrind f951 < t2.f90'. I'm not sure if that's the right way, as there is no
documentation on how to use valgrind together with the compiler. See PR15039.
I'll attach the output below.

I reduced the original testcase a little more:
INTEGER, POINTER :: P => NULL()
P => NULL()
END
commenting out either assignment makes the failure disappear.
