Subject: Don't enable dynamic libraries unloading at END time by default
X-Git-Tag: v1.01~2
X-Git-Url: http://git.vpit.fr/?p=perl%2Fmodules%2FTest-Valgrind.git;a=commitdiff_plain;h=763b4e655388ce7341369cf73fd7758360821b3d

Don't enable dynamic libraries unloading at END time by default

This makes the error stack traces unreadable because valgrind tries to resolve the symbol names after they were unloaded (and not when the error occurs).

+When set to true, all dynamic extensions that were loaded during the analysis will be unloaded at C<END> time by L<DynaLoader::dl_unload_file>.

+Since this obfuscates error stack traces, it's disabled by default.
