Subject: More lax valgrind version parsing
X-Git-Tag: v1.19~4
X-Git-Url: http://git.vpit.fr/?p=perl%2Fmodules%2FTest-Valgrind.git;a=commitdiff_plain;h=f69f14a04c9b6c47bb1468e192977632cc1c854a

More lax valgrind version parsing

If valgrind ever decides to add a full stop at the end of the output of
"valgrind --version", then the (?!\.) in the version parsing regexp will
cause unexpected backtracking which will result in an invalid version.
