valgrind log (bzip2)
I'm trying to run the wine tests on my laptop under valgrind. When running the
graphics tests, valgrind goes nuts in the i965 driver. The first time I ran it,
It threw an error that it hit over 10 million (!) errors and was quitting.
After a couple hours playing with suppressions and eventually exluding
practically anything invoving i965/libdrm_intel.so, I was able to get results.
As a testcase, I tried valgrinding glxgears instead, and was able to reproduce
it there as well:
==19571== More than 10000000 total errors detected. I'm not reporting any
more.
==19571== Final error counts will be inaccurate. Go fix your program!
==19571== Rerun with --error-limit=no to disable this cutoff. Note
==19571== that errors may occur in your program without prior warning from
==19571== Valgrind, because errors are no longer being displayed.
to reproduce:
valgrind -q --trace-children=yes --track-origins=yes --gen-suppressions=all
--leak-check=full --num-callers=20 --workaround-gcc296-bugs=yes
--vex-iropt-register-updates=allregs-at-mem-access glxgears
let glxgears run for a few seconds, then close
valgrind 3.9.0
