[Bug pch/36606] New: segfault when a pch is included through a header file

[davorin dot ucakar at gmail dot com]

A chain of files like pch -> .h -> .h -> .cpp (pch is included through 2
headers) crashes gcc. This bug is a regression from 4.2.x.

Here's a base64 encoded .tar.gz with example source (sorry, but where's any
option to send an attachments here on buzilla? :/):
