SubjectRe: cc1plus invoked oom-killer: gfp_mask=0x280da, order=0, oom_adj=0

Ah, you're running it on the "c++" utility and it's reporting the stats for
that, but how it works is that "c++" (and "gcc", "g++", et al) is just a
driver, that parses the command line arguments and shells out to the actual
compiler ("cc1plus"), assembler and linker to get them to do all the work.

If you add "-v --save-temps" to the c++ invocation, it'll show you the
separate command lines it executes for the subprograms; the first invocation
will be of cc1plus, using the -E flag to generate the preprocessed source into
a .ii file, it's the second invocation you want, the one which uses the
"-fpreprocessed" flag and names the .ii file as input, which is the one that
actually then compiles the pre-processed source into assembly. For fuller
explanation, see the GCC wiki:
