[DragonFlyBSD - Bug #2344] dmalloc assertion: (*bmp & (1LU << bno)) == 0 in memfree

[Venkatesh Srinivas via Redmine <bugtracker-admin@xxxxxxxxxxxxxxxxxxxxx>]

Issue #2344 has been updated by Venkatesh Srinivas.


Hi,

I believe the test program posted above is wrong. Specifically, after realloc(), it checks if the original pointer, not the new return from realloc, is nonzero, and then free()s. This is not okay -- after a nonzero return from realloc, the original pointer has been released and is no longer valid.

Thanks,
