That tells the compiler to produce 64-bit output, it doesn't change
how much memory it has available, and is likely to use more memory to
represent the larger pointer types.

Do you mean you've put all the code in a single file? If yes, then of
course splitting it up into smaller files will use less memory.

Good grief.

This error isn't even coming from GCC, it's coming from the assembler,
which is part of Solaris and not part of GCC. It's trying to assemble
a file that is at least 15 million lines long. That's probably your
problem. Try splitting Main.c into smaller files.
