X-Spam-Level:
Package: valgrind-calltree
Version: 0.9.6-3
Severity: important
calltree segfaults on call to calloc:
first = (unsigned int*) calloc (USHRT_MAX, sizeof (unsigned int));
on a program (multi-threaded) that has no detected memory errors under valgrind
(memcheck).
The exact message is:
==3246== Process terminating with default action of signal 11 (SIGSEGV):
dumping core
==3246== Address not mapped to object at address 0x4B
==3246== at 0x40219E1C: (within /lib/libc-2.3.2.so)

==3246== by 0x805787A: CBody_SplitMultiple (cbody.c:1066)
The error occurs in one of children threads. For the same program Valgrind
reports:
==3262== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)
==3262== malloc/free: in use at exit: 0 bytes in 0 blocks.
==3262== malloc/free: 59582 allocs, 59582 frees, 639824038 bytes
allocated.
While a similar analysis on a RedHat 7.3 distribution with:
valgrind --version: valgrind-1.9.3
calltree --version: valgrind-1.9.6
does not segfault, though is complains about:
Thread 1: status = WaitJoiner, associated_mx = 0x0, associated_cv = 0x0

Dear all,
I have restored my piece of software to a status as close to the one it had on
07/09/2004 using our CVS (this should be a very good approximation of what it
really was). I have not touched anything else on my current system though
(up-to-date with debian testing) and have upgraded to the unstable versions of
valgrind and valgrind-callgring. Finally, I tried to run the very same tests I
did last year and... the bug is gone ! Callgrind produces a callgrind.out file
which seems in every aspect correct.
I really want to thank you for the amazing job you do and tell you how greatly
appreciated your follow up of bug reports are.
Shan
