Bug ID: 362920
Summary: valgrind refuses to execute pkcs11-tool binary from
OpenSC: assertion 'tst->os_state.pthread - magic_delta
== self' failed
Product: valgrind
Version: 3.11.0
Platform: MacPorts Packages
OS: OS X
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: memcheck
Assignee: [email protected]
Reporter: [email protected]
I have built OpenSC from master branch on Github.com/OpenSC/OpenSC. I am trying
to verify its memory usage with valgrind. I am trying to execute command
valgrind pkcs11-tool -t -l
to perform pkcs11 tests. It fails with this assertion:
valgrind: m_syswrap/syswrap-amd64-darwin.c:507 (void wqthread_hijack(Addr,
Addr, Addr, Addr, Int, Addr)): Assertion 'tst->os_state.pthread - magic_delta
== self' failed
Reproducible: Always
Steps to Reproduce:
1. On Mac OS X 10.11.4 with Xcode-7.3.1 install valgrind via Macports.
2. Clone, build and install https://Github.com/OpenSC/OpenSC.git
3. Run "valgrind pkcs11-tool -t -l"
Actual Results:
$ valgrind pkcs11-tool -t -l

Note: see also the FAQ in the source distribution.
It contains workarounds to several common problems.
In particular, if Valgrind aborted or crashed after
identifying problems in your program, there's a good chance
that fixing those problems will prevent Valgrind aborting or
crashing, especially if it happened in m_mallocfree.c.
If that doesn't help, please report this bug to: www.valgrind.org
In the bug report, send all the above text, the valgrind
version, and what OS and version you are using. Thanks.

Expected Results:
Valgrind analysis of memory usage by pkcs11-tool and dynamic libraries it
loads.
Mac OS X 10.11.4. Xcode-7.3.1. OpenSC master branch (probably less relevant).
Valgrind-3.11.0 installed by Macports.
