gcc 5.3.1 segmentation faults when compiling qt5/qtbase [dev]

[mipohjan]

* gcc version 5.3.1 20160413 (Ubuntu 5.3.1-14ubuntu2)
* Ubuntu 16.04 LTS (Xenial)
* gcc from the Ubuntu repositories
* Qt cloned from http://codereview.qt-project.org/qt/qt5 [dev] branch
* Qt configured with:
./configure -openssl -R . -opensource -confirm-license -nomake tests -verbose -prefix . -nomake examples -no-widgets -force-debug-info
* and build with:
 make module-qtbase

The bug has been reported to: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71622
and the preprocessed file and gcc output of the segmentation fault can be find from that link.

you need to build and submit the report without precompiled headers. In this form it is not reproducible.

The bug has been marked as duplicate to: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63319

And the problem is that it's not reproducible without precompiled headers..
