Subject: Increase allowed size of a back-trace to 500 frames.
X-Git-Tag: svn/VALGRIND_3_8_0~183
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5dec28d4afccf2995152d43568aca198c03e5253;p=thirdparty%2Fvalgrind.git

Increase allowed size of a back-trace to 500 frames.
This limit is large enough for all practical purposes. It exists
only to sanity check the value specified with --num-callers.
Be frugal in record_ExeContext_wrk and only allocate on the stack
as many frames as needed.
Testcase included.
