Compiler crash when building libreoffice with debug

[Pranav Ganorkar]

Hi,

When trying to build sfx2 module with debugging symbols , I get the
following build error:

make sfx2.clean && make sfx2 debug=t

Seems to be related to this gcc bug:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69149

without debug , sfx2 module builds fine.

My GCC version is 5.3.0 and I am building it on 64-bit Archlinux.

Does anyone know what can be the solution for it?

Regards,
Pranav
