On DMD I got some strange out-of-memory errors with the current 2.054 version.
I tracked it down to allocations happening during garbage collection.
Has something fundamental in the GC implementation changed in the latest
release? It used to work, but seems to be completely disallowed now. I think it
is quite a strong requirement to not make any allocations from within
finalizers and makes them just another bit more useless. (In my case I have
some logging going on which needs dynamic allocations for formatting
(Appender)).
Hi, I was the one who submitted the patch. The situation before the patch was
that allocating memory from a finalizer of a collected object inevitably lead
to memory corruption (which is, as you may know, devilishly hard to track
down). Ideally, someone would rewrite the appropriate parts of the GC to allow
safe throwing and allocations from finalizers, but that hasn't happened yet.
I started on the rewrite, but it's a pretty big change so I'm considering
trying out Leandro's GC instead. It would require some work as well, but the
code is cleaner and it already supports precise scanning, so it may be a better
starting point.
IIRC Leandro's GC doesn't work on windows.
