Re: [PATCH] Combine location with block using block_locations
Sorry for breaking these tests.
This problem is very hard to reproduce. However, I had a patch to fix
another compile-time problem which may be related to this one.
http://gcc.gnu.org/ml/gcc-patches/2012-09/msg01491.html
After applying the patch, the PCH related bugs are not showing any
more on my machines.
