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.
