tracking down insane memory leaks

tracking down insane memory leaks

One of the best parts of AddressSanitizer is the built in leak sanitiser. However, sometimes it's not as clear as you might wish!

I0> /opt/dirsrv/bin/pwdhash hello                            

==388==ERROR: LeakSanitizer: detected memory leaks

Direct leak of 72 byte(s) in 1 object(s) allocated from:
    #0 0x7f5f5f94dfd0 in calloc (/lib64/
    #1 0x7f5f5d7f72ae  (/lib64/

SUMMARY: AddressSanitizer: 72 byte(s) leaked in 1 allocation(s).

"Where is /lib64/" and what can I do with it? I have debuginfo and devel info installed, but I can't seem to see what line that's at.
