Comment #14 on issue 9458 by [email protected]: Valgrind reports memory
leak in _NPN_RegisterObject in
LayoutTests/http/tests/history/redirect-js-form-submit-0-seconds.html
http://code.google.com/p/chromium/issues/detail?id=9458
This can also be reproduced with the command
sh tools/valgrind/valgrind_webkit_tests.sh
LayoutTests/http/tests/misc/timer-vs-loading.html
(after you disable the suppression for it in
tools/valgrind/memcheck/suppressions.txt).
Here's a current backtrace:
144 bytes in 3 blocks are definitely lost in loss record 653 of 1,005
