Ping [PATCH, fortran] PR 41936 Memory leakage with allocatables and user-defined operators

[Paul Richard Thomas]

Dear Dominique,

Without the patch applied, trunk shows 360 bytes definitely missing in
3 blocks for the original testcase and 9 out of 92 allocs did not have
corresponding frees. WIth the patch, I get:

==20527==
==20527== HEAP SUMMARY:
==20527==     in use at exit: 0 bytes in 0 blocks
==20527==   total heap usage: 92 allocs, 92 frees, 54,502 bytes allocated
==20527==
==20527== All heap blocks were freed -- no leaks are possible
==20527==
==20527== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 2 from 2)
--20527--
--20527-- used_suppression:      2 glibc-2.5.x-on-SUSE-10.2-(PPC)-2a
/usr/lib64/valgrind/default.supp:1286
==20527==
==20527== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 2 from 2)

Not only that, it bootstraps and regtests OK.

So it definitely does what it is advertised to do :-)

OK for trunk and, I would suggest 4.9.

Cheers

Paul

PS ifort 13.01 has exactly the same fault....
