 Ups, this bug didn't shown up in my search-list ...
 Issue fixed for 4.7, 4.8, and trunk at rev 204635-204637.

I recently stumbled on a similar problem again with a recent Cygwin/GCC
combination.
Looking at the fix included in GCC, it does look slightly different from what
was first suggested here.

Could someone more knowledgeable than me have a look and tell whether the
included fix is fine or incomplete?
If incomplete, I'll be happy to open a new bug report.

See here for my report on cygwin's mailing-list:

This is fixed with FSF GCC 4.7.2.

I can confirm this also happens on the current Cygwin distribution with GCC

4.6.3 bootstrapped with the Cygwin GCC 4.5.3 distributed in the gcc4 package.



I'm trying to build GCC 4.7.2 to see whether the bug is still present there.
