Non capturing parenthesis in regexp causes seg fault.

[Arran Cudbard-Bell]

Hi,

Got this on my 32bit intel box running Ubuntu Linux 6.10

if("%{User-Name}" =~ /(?:.*)/){
}
---
++? if ("%{User-Name}" =~ /(?:.*)/)
    expand: %{User-Name} -> anonymous

Program received signal SIGSEGV, Segmentation fault.

Normal expressions work fine.

Thanks,
