Bug#667969: gcc-4.6: r185758 included in version 4.6.3-2 breaks GCC on hppa

[Dave Anglin <dave.anglin@bell.net>]

Package: gcc-4.6
Version: 4.6.3-1
Severity: important

After building and installing version 4.6.3-2, I found the new
version would hang compiling various files in pointer_set_insert.
GCC is unable to bootstrap itself.

This is GCC PR middle-end/52894.

The fix that introduced this problem was also applied to 4.5, 4.7
and the trunk.  Debian version 4.7.0-2 has the same problem.
