Hi,

certainly strange.  MathLib0 is one of the largest modules gm2 has to
compile (and one of the most complex in terms of scoping) thus I'd
expect it to exercise the memory system pretty heavily (and the
garbage collection routines within gcc in particular). I'd also
expect it to allocate much memory, for the life of various scopes.

How much memory has your machine got? You could try running `top' in
one window while the compile is executed in another and watch for
available pages - in particular watch and see whether the machine runs
out of memory.. (maybe gm2 is in error as it is not freeing memory
appropriately and GNU/Linux throws in the towel),

hope this helps,
Gaius
