251. Note: see also the FAQ in the source distribution.
252. It contains workarounds to several common problems.
253. In particular, if Valgrind aborted or crashed after
254. identifying problems in your program, there's a good chance
255. that fixing those problems will prevent Valgrind aborting or
256. crashing, especially if it happened in m_mallocfree.c.
257.  
258. If that doesn't help, please report this bug to: www.valgrind.org
259.  
260. In the bug report, send all the above text, the valgrind
261. version, and what OS and version you are using.  Thanks.
