http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60504 --- Comment #10 from Mikael Pettersson --- (In reply to Eric Botcazou from comment #9) > That's good news, thanks. Did you do a testsuite run for all languages? Sorry, didn't have time for that -- the repeated 4.9 builds and tests caused other build-and-test jobs to pile up and I need to get those done first.

With Eric's suggested patch I still got: Correction: Eric's suggested patch does work. In my previous attempt I applied his patch and only did an incremental rebuild, and that didn't resolve all testsuite regressions. Now I've done a clean build from scratch and the testsuite regressions are in fact gone.

At that point I aborted the whole thing. All FAILs were "Execution terminated by abort of environment task". I'm going to try a revert of the unwind changes next, as soon as I can identify the corresponding svn revision numbers.
