Error 203 (heap overflow) running Lazarus on Arch Linux

Do you have /etc/fpc.cfg or ~/.fpc.cfg? You should have that correctly configured to build Lazarus from source.

Yes, I have them both, but I can't tell if they're correctly configured.

This is the ~/.fpc.cfg file:  http://pastebin.com/vwq760jV
And this is the /etc/fpc.cfg file:  http://pastebin.com/fzYWyGiy

Yes, I have them both, but I can't tell if they're correctly configured.

In this case, only ~/.fpc.cfg will be read. The correct configuration is a single -Fu that points to your fpc units directory, in this case:
-Fu/home/mati/fpc-3.0.0/lib/fpc/$fpcversion/units/$fpctarget/*
I don't know if that's correct on your machine, it should contain rtl + each individual packages directory, for which the * is for. Right below them, are the .ppu's and .o's. Other than that, everything else is wrong (unless you customize and you know what you customize and how to configure them).

-Fu/home/mati/fpc-3.0.0/lib/fpc/$fpcversion/units/$fpctarget/*

What about just renaming ~/.fpc.cfg to see if make would then use /etc/fpc.cfg?

Will need to check whether that file contents is correct either.
