Bug ID: 356457
Summary: valgrind: m_mallocfree.c:2042 (vgPlain_arena_free):
Assertion 'blockSane(a, b)' failed.
Product: valgrind
Version: unspecified
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: joost.vandevond...@mat.ethz.ch
Our nightly tester runs a few thousand testcases, and usually this goes all
fine. However, seemingly some rare condition can trigger the following assert:

Note: see also the FAQ in the source distribution.
I have attempted to reproduce this (running exactly the same commands and
binary, etc.) but this didn't fail. The error appears to happen before our
executable is really running, so maybe something is wrong on startup ?
