hi,

I have tried to build the hunt-sql package on Windows 7 32bit(with 3GB RAM), dmd and ldc2 both failed with default option "out of memory".

And after trying with `dub build-mode=singleFile`, dmd compiles all the .d file, but "out of memory" when linking. and ldc2 says 'single linking is not supported'.

we should at least compiles the program, we need to use memory the OS gived to US, not just "out of memory" and then quit.


and I tried to supply gc options to dmd and ldc2 it self, has no effects at all.

detailed err info:

This is a well-known issue but also heavily depends on the compiled code (CTFE usage and recursive template instantiations etc.). -lowmem usually helps, but isn't supported with dub and DMD (but with LDC since v1.17).

Has been fixed in the meantime (since dub bundled with LDC v1.18).

just tested, -lowmem doesn't help even with LDC version 1.18.0, out of memory when linking again, but it seems it's working when compiling.

yes, dub bundled with ldc in V1.18 just linked successfully using both dmd and ldc.


Thanks!
