The following code: ``` __gshared ubyte[0x1000000 - 1] BUFFER = 0; void main() {} ``` When compiled with: dmd -g -m64 Will produce an exe of size: 21_378_560 bytes Without -g, it'll produce an exe of size: 415_744 bytes It only happen on windows, only with DMD, only with that -g option

It is also happening with -m32mscoff As discussed in the IRC, it seems to be related to COFF stuff, i'm not knowledgeable enough to dig deeper
