[Gc] Issue with Valgrind in threading

[Agnius Vasiliauskas]

Hi,

I'm trying to use boehm garbage collector. When I run Valgrind memory leak
detector in my
program which uses GC - i've got such messages: (GC was compiled with POSIX
thread support):

Leak_PossiblyLost|====|144 bytes in 1 blocks are possibly lost in loss
record 1 of 1| ||Call stack:|
/usr/lib/valgrind/vgpreload_memcheck-x86-linux.so||0x402C109: calloc|

/home/agnius/Downloads/bigint/main.c|225|0x804B284: main|

seems like some memory leak issue when creating posix threads ?

Thanks for help.
