isn't it possible to reduce the amount of debuginfo put into the object
files? If "-g" is used to compile gcc, can you try with "-g1" (or even
with "-g0")? gcc is now a C++ application and it adds huge amounts of
debuginfo data. And in theory passing "-Wl,--no-keep-memory
-Wl,--reduce-memory-overheads" to the linker flags might also help.
Fighting with OOM is not a uncommon issue in Linux distros on 32-bit
platforms these days.
