 I did "unlimit datasize" and re-tried the build.
 
 It crashed the same way.
 
 I had a "top" window up at the same time, and the "SIZE" coloumn
 maxed out at around 71MB for the cc1 process.
 
 virt68k: {14} limit
 cputime      unlimited
 filesize     unlimited
 datasize     65536 kbytes
 stacksize    2048 kbytes
 coredumpsize unlimited
 memoryuse    122220 kbytes
 vmemoryuse   unlimited
 descriptors  128 
 memorylocked 40740 kbytes
 maxproc      160 
 maxthread    2048 
 sbsize       unlimited
 virt68k: {15} 
 
 is what I tried with.
 
 Note, I beleive the dynamically allocated memory is done by mmap,
 so is not accounted for in the "datasize" limit(?)
