Is this really the important thing? Seems like -g0 saves disk space, not memory? (Loading the symbols into a debugger may require lots of memory, but that is not the issue here.)
Header-only C++ packages require the compiler to effectively process one huge source file instead of a bunch of smaller ones, thus the need for a huge amount of memory in some cases. The suggestion to drop -pipe might be helpful since it pushes more of the resource use from memory to disk.
