[hardening-discuss] Bug#462682: hardened-c++: dies due to "Nested quantifiers in regex"

[Aaron M. Ucko]

Package: hardening-wrapper
Version: 1.4
Severity: important

hardened-c++'s attempt to check for being run directly (rather than
as, say, g++) backfires due to insufficient quoting:

$ g++ -dumpversion
Nested quantifiers in regex; marked by <-- HERE in m/hardened-c++ <-- HERE $/ at /usr/bin/g++ line 74.

To avoid this problem, please either rework the logic to use substr,
pre-quote $self, or surround its uses with \Q ... \E to account for
the embedded + characters.

Thanks!
