Thanks for your quick response. I would like to point out that on every
compiler and machine I've used, the behavior of signed overflow may not be
defined -- but it's always been consistent.

Hmm, -flto and -fwhopr are in common.opt. The -Wpsabi and -Wabi options are
not, but I fail to see why this is the fault of LTO.
I have a patch to move the -flto / -fwhopr postprocessing to common code.

should be fixed up.

these old bug reports and associated testsuite failures? It also provides a

--- Comment #9 from dominiq at lps dot ens dot fr 2009-10-31 17:13 ---
The '.*?' is the non greedy form of '.*'.
I have learnt regexps at a time when this was not available on all regexp
engines, so I always forget such constructs.
I think pr41890 is a duplicate of this one.

Confirmed with current 4.4 branch. 4.5 doesn't segfault for some reason, but
we run into the same invalid code.

The bug was originally reported in the (Germany-language) mikrocontroller.net
forum, and I confirmed the bug on my local GCC 4.3.2 setup before asking
Frank to submit it as an official bug report.
