Ugh, don't know about ARM build but GDC itself currently supports 
2.063.2 version for both 4.8 and 4.9 branch.

Generally, only latest DMD release + latest library release are 
guaranteed to work. It is a big and complicated problem to get 
this right.

First, all 3 major compilers have incompatible ABI so they need 
whole own library stack built starting with druntime / phobos.

Second, bigger cross-platform programs like vibe.d have lot of 
version definitions that change behavior considerably (for 
example, various event drivers for vibe.d), on top of usual OS / 
processor versioning.

Combined together that creates an exponential configuration count 
that is almost impossible to test manually. Sonke (vibe.d author) 
has recently recognized what a disaster this creates and right 
now adding Continuous Integration testing is high priority target 
- but this is still work-in-progress.

As a result, with every small step from configuration common 
among library/program developers (usually it is latest DMD + 
x64_86 + Linux/Windows) probability of something breaking bad is 
damn high.

Actually, I don't know if vibe.d has ever been tested with GDC at 
all.

If rebuilding GDC from sources so that it will catch 2.063.2 
frontend version is an option - it may help.
