Hello,

> with the latest gcc 2.2 snapshot ?

I take it you meant 4.2. I've checked and this bug is not present in
4.1.2, 4.2.2 or the current branch (to become 4.3.0) on linux. I have
also checked and it does not appear on mingw for 4.3.0. So, this is a
mingw-only, 4.2-only bug, is that correct?

Are you building this snapshot yourself or

I'll be more than happy to help you find out the possible bugs in
gfortran-4.3 or the possible bugs in your code exposed by
gfortran-4.3, if you start down that path. As a side note: mingw
doesn't officially support gcc-4.x for any value of x smaller than 3.

> Can I expect this bug to be solved in the 4.2.3 version ?

No. The 4.2.3 release process has begun and the version should be
officialy released in the next 24 hours.

For a possible 4.2.4 fix, the rule is that we only fix regressions: if
that was working on the 4.1 branch, we can consider fixing it on a
later released branch. Otherwise, we would need a particularly
compelling reason.

> or is it possible to backport to gcc 4.2 the correction from gcc 4.3 ?

Do you have a PR number for this bug? Or does this ring a bell to
someone? I don't know who fixed that issue (nor if he did so
intentionally).

Regards,
François-Xavier
