Yeah, that one got reduced to 
https://issues.dlang.org/show_bug.cgi?id=13229 .

Anyway, I got only a couple of bugs I could blame the compiler 
for, and some of that couple disappeared after upgrading to a 
more recent version.

If I had to remember a language-related problem, the biggest one 
for me was that my program usually hit an out-of-memory error 
very soon.  It worked fine when compiled with 64-bit DMD but 
failed to collect the garbage in time with 32-bit DMD and with 
recent LDC.  GDC was a minor version behind, so it didn't compile 
at all from a certain point because of a compiler's stack 
overflow - same as with e.g. DMD 2.064 or older.  But again, I 
switched from 32-bit to 64-bit DMD, and the problem vanished, 
with a little speedup as a nice bonus.

It is not the first time I had an unexpected out-of-memory 
problem, but it occurs only when my programs get complex, so (1) 
in each case, I was not sure I can blame the garbage collector, 
and (2) this is usually hard to reduce.  I'll probably have 
another try at reduction (but I won't have time for that in the 
next two weeks).
