          Issue ID: 20562
           Summary: [dmd] Memory allocation failed (ERROR: This is a
                    compiler bug)
           Product: D
           Version: D2
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com

After updating to 2.088.1 from 2.087.1, my project no longer compiles with dmd
under Windows and just throws an OutOfMemoryError.

I bisected it to https://github.com/dlang/dmd/pull/10446, which adds a stack
size linker parameter to dmd's compilation, and thus breaks mine.

          msg = "(DC) DMD%s %-(%s, %)".format(targetSuffix, dmdSources.map!(e
=> e.baseName).array);

 +        ].chain(extraFlags, platformArgs, flags["DFLAGS"], sources).array;
      return new DependencyRef(dep);
I don't know enough. Assuming it's there for a reason and can't be reverted, can we at least increase the size? Or is there some other way for me to be able to keep using dmd? To test (assuming Windows):
