Description Ivan Sedo 2005-07-08 18:50:05 UTC

Description of problem:
I'd like to use tools from 
http://multivalent.sourceforge.net/
but if I try to execute (I only tried it on) Validate, I get this error

Comment 1 Thomas Fitzsimmons 2005-10-01 21:42:52 UTC

This should probably be filed at gcc.gnu.org/bugzilla.  It'd be great to have a
minimal test case for this.  Reassigning to Tom Tromey.

Comment 2 Tom Tromey 2006-01-23 22:00:55 UTC

Test case:

import java.util.regex.*;
public class t {
  public static void main(String[] args) {
    System.out.println(Pattern.compile("(?i)\\.pdf$"));
  }
}

Comment 3 Tom Tromey 2006-01-26 00:45:42 UTC

Ito's regex fixes in Classpath fix this bug.
I'm investigating whether to pull these into gcc4.1 / fc5

Comment 4 Tom Tromey 2006-02-13 23:26:39 UTC

I put the patches in 4.1.
They are either in rawhide now, or will be shortly.
So, I'm closing this.
