assert fail in taintgrind

[msoos]

When I run the example:

$ valgrind --tool=taintgrind --file-filter=test.txt --taint-start=0 --taint-len=1 --critical-ins-only=no gzip -c test.txt

I get:

$ valgrind --tool=taintgrind --file-filter=~/test.txt --taint-start=0 --taint-len=1 --critical-ins-only=no gzip -c  ~/test.txt

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.

Version of valgrind used is 3.9.0. I used the GIT version of taintgrind. Everything compiled without any warnings.

PS: Thanks a lot of this tool, would be awesome to use it!
