That's not GDC related though ;-)


It's a bug in GCC, which is triggered only when building GDC, 
not when building GCC with c,c++ and lto (same configuration 
otherwise).


Sorry, I was wrong; I confused myself by building GCC_5.1.0 as 
stand-alone (argh).


Building GCC-5.2.0 to GCC-5.4.0 (with or without GDC) fails with 
the error mentioned above.


I'll try and contact the GCC team; maybe they have a suggestion 
for a fix or workaround.

GCC-4.9.3 builds OK.
GCC-4.9.3+GDC builds OK.
GCC-4.9.4 builds OK.
GCC-4.9.4+GCC fails.

GCC-5.1.0+GDC fails (due to register_main_translation_unit)
GCC-5.2.0+GDC fails (internal compiler error)
GCC-5.3.0+GDC fails (internal compiler error)
GCC-5.4.0+GDC fails (internal compiler error)

This means my latest GDC is 4.9.3.

When the current build is finished, I'll try and revert back to 
an old gdc-5 (before the register_main_translation_unit change) 
and see if that will build.

I'm not so sure such a change would happen in a minor release.  But in
any case I'd say it can't be assumed that a version branch will work
with anything except the latest release in that series.
