yes. this is known behaviour of cc.
(although I havent seen it with libiconv specifically)

certain obscure optimization cases, explode, so to speak, taking extreme
memory usage and disk space for it to "traverse the problem space", if you
will.

Your choices are:

a) wait for a long time, and it will eventually complete, if the machine
doesnt run out of resources

b) reduce the optimization flags to -xO2 or -xO3
