And that critical size isn't very large.

I cannot compile anymore :
Unable to fork: Cannot allocate memory

I cannot use separate compilation to mitigate the problem as some symbol are not emitted properly (so I get linker errors).

Hopefully, dmd is fast because it doesn't use any GC.

Are there bugzilla entries for these?

They are for released version of dmd. For the new beta, things have changed, but it didn't reduced them to a simple test case yet.

Wasn't this a problem long before? My D environment on linux fails to unittest Phobos code with exactly same error message and I remember this was discussed in newsgroups.

This is still the situation, depending on how much memory your machine has. I used to run the Phobos unittests with make -j6 to speed things up, but recently I can't do it anymore without getting the above error message, because std.algorithm will consume all the memory, leaving no room for the others.

I remember having DMD do that on me as well, when one time I used std.regex.ctRegex a bit too eagerly. I think (part of?) the problem is that CTFE allocates memory but never frees it, so too much CTFE will cause DMD to run out of memory.

So reduced thing with dmd from git, and this still boils down to that : http://d.puremagic.com/issues/show_bug.cgi?id=8997

Just now, I posted another fix for bug 8997. https://github.com/D-Programming-Language/dmd/pull/1667

I think http://d.puremagic.com/issues/show_bug.cgi?id=9485 is about this bug too.

OK, tested and it does work ! otsukare sama !

But . . . This issue was hidding another one. I still have linking issue. I'm dustmiting it right now, but this will take a while !
