            Bug ID: 18654
           Summary: mcheck should warn if threads exist
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: jan.kratochvil at redhat dot com

  Target Milestone: ---

-lmcheck (MALLOC_CHECK_) + -pthread should warn the user.

In reality -pthread always gets indirectly linked so -lmcheck should just check
if a new (second) thread has ever been created in this process.

Maybe it is enough if mabort() does this check - that the crash is due to
unsupported mcheck usage and not due to the program's bug.

One does not immediately realize all the possible reasons of a crash.
