Hello Michael,

mcheck is known to be unusable for quite some time with multi-threaded applications:

	https://sourceware.org/bugzilla/show_bug.cgi?id=9939

Until yesterday (including many hours of bug-hunting) this fact was not known to me, thus, I would like to suggest to add a note in the mcheck(3) manual page (and probably in the GLIBC documentation as well). I think one sentence in the NOTES section should suffice.

Thanks in advance!

Best regards
Tolga Dalman

It is sometime since your mail, but FYI, notes on the thread-non-safety of mcheck() were added to the page in the last months.

Thanks,

Michael
