[dm-devel] multipathd leak

[Christophe Varoqui <christophe varoqui free fr>]

Hello,

can you look into this leak reported by valgrind :
(valgrind --show-reachable=yes --leak-check=full -v multipathd/multipathd -d)

==2957== 16384 bytes in 1 blocks are definitely lost in loss record 10 of 10
==2957==    at 0x11B1BE96: malloc (vg_replace_malloc.c:149)
==2957==    by 0x11D41B61: dm_task_run (in /lib/libdevmapper.so.1.01)
==2957==    by 0x40444D: waiteventloop (main.c:481)
==2957==    by 0x40464C: waitevent (main.c:537)
==2957==    by 0x11C2FB1B: start_thread (in /lib/libpthread-2.3.5.so)
==2957==    by 0x1243B272: clone (in /lib/libc-2.3.5.so)

We miss a dm_task_destroy in the stop_waiter_thread path.
It seems related to the pthread_kill trickery you are familiar with.

Didn't we conclude the trickery was due to a glibc bug earlier ?
If so, can this be fixed in updates or  will it have to wait till RHEL5 ?
