memory leak in __archive_read_get_extract #409

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The latest git code of libarchive (not reproducible in latest release) has a 
memory leak. It seems the variable extract (line 100, archive_read_extract2.c) 
is never free'd.

Seems to happen independent of the archive used, just bsdtar -xf on a random 
file.

valgrind output:
==6850== HEAP SUMMARY:
==6850==     in use at exit: 24 bytes in 1 blocks
==6850==   total heap usage: 91 allocs, 90 frees, 133,036 bytes allocated

Thank you!

I believe this is fixed in git commit d24e79e
