Thanks for your response !
I think the cc1 process is somehow operating in slow motion,
even though I've pinned the CPU frequency to 1.8 GHz (it 
will crash if I don't reduce it soon - so this is not a "slow
machine" issue!) .

cc1 is writing about one line every 2 minutes to its assembler output file:
...
12:10:14 write(3, "3\n.L2088:\n\tmovq\t(%rbx), %rdi\n\tca"..., 4096) = 4096
...
12:12:24 write(3, "%edi\n\tmovq\t32(%rbx), %rbx\n\tcall\t"..., 4096) = 4096
...

I think this is because it has to hold a huge chunk of "contiguous" 
memory :

$ ps -o 'vsz rss %mem' -p 3863
   VSZ   RSS %MEM
258444 125752  7.3

So it is trying to hold @1.25GB of contiguous RAM. (my machine has 2GB).

These memory requirements are solely due to the size of the .c file (1.8MB) .

Why can't they be reduced somewhat?
