Yes. > The values of memory required are definitely not of order 1GB. There are OSes which can be booted in less than 100MB. Have you actually looked at what is being compiled for gimple-match.o?

You could try compiling that file without optimization, or you could try building the compiler on a machine with more memory then copying it to your rpi.
