digitalmars.D - 'out of memory' error compiling on windows

hi,

i got an 'out of memory' error when compiling lage(r) d files
using dmd v1.061 on windows.
on freebsd/linux the same dmd version compiles the d source without problems.

interesting is that i get the same error when compiling a similar c source
code using the digital mars c compiler.

anyone knows which wall i'm hitting in the dmd/dmc compiler backend ?

the source files in question are generated using the following d program
(mkdata.d) from binary blobs (e.g. zip files) :

howto reproduce :
dmd mkdata
mkdata foo.zip > data.d
dmd -c data.d

for dmc:
mkdata -cxx foo.zip > data.c
dmc -c data.c

the problem starts when foo.zip is larger than 800kb giving a 4+ mb data.d

import std.string;
import std.file;
import std.path;

{
	writefln("const string name_" ~ name ~ "=\"" ~ name ~ "\";");
	writef("const ubyte[] data_" ~ name ~ " = [");
	foreach(n,d;data)
		writef("0x%02x,",d);
	writefln("\n]; // end of data_" ~ name);

	writefln("static unsigned int size_" ~ name ~ "=%d;",data.length);
	writef("static const char data_" ~ name ~ "[] = {");

	foreach(n,d;data)
	{
		if( (n % 16) == 0)
			writef("\n// %d : 0x%04x\n",n/16,n);

	}
