The last target specific change of 4.9 SVN tree was r221686 | olegendo | 2015-03-26 16:46:51 +0900 (Thu, 26 Mar 2015) | 6 lines So if the test case fails with the vanilla gcc 4.9 rev 223898 built on Debian, the issue isn't caused by the target specific changes or it depends on the environment weirdly. I'll try a new bootstrap on 4.9 SVN rev. 224552 and see it's ok with the test case. It'll take ~2 weeks, though. Perhaps it's better to run your cc1 under gdb or strace and see where/why that segfault happens.
