           Summary: request to document that mcheck is not thread safe.
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: manual
        AssignedTo: roland@gnu.org
        ReportedBy: peeter.joot@gmail.com


Attempting to use -lmcheck on a threaded program, I was not able to locate the
error in the source associated with an apparent mcheck() MCHECK_HEAD status
result.  I found on stackoverflow:

http://stackoverflow.com/questions/314931/glibcs-lmcheck-option-and-multithreading

saying that mcheck is not actually thread safe, referencing the following bug
report:

http://sourceware.org/bugzilla/show_bug.cgi?id=6547

This bug is opened to request that the non-thread-safe nature of mcheck() be
documented explicitly in the libc info page 'Heap Consistency Checking'.
