As a start, it would be useful to have preprocessed source so that it can be looked at without the rest of the package. One interesting thing is try to compile it (the preprocessed testcase with the same command line options) on x86_64 with -m32 -fmem-report and see where the memory is spent there (of course, on x86_64 it will take slightly more memory as pointers are larger). Removing -flto could save some memory; otherwise, it ddepends on where most of the memory goes, if into optimizations, perhaps disable some of them or compile with -O1 etc., either for the whole file or just some of the largest functions. If the memory is eaten already in the C++ FE, like instantiation of excessively large (or too many) templates, then splitting the source might be the only way to make it compile.
