ps auxww
...can show you how much memory is in use for the entire process.

It's commonly combined with grep, like:
ps auxww | head -1
ps auxww | grep my-program-name

Have a look at the %MEM, VSZ and RSS columns.

But being out of memory doesn't necessarily lead to a segfault - it can (EG
if a malloc failed, and some C programmer neglected to do decent error
checking), but an OOM kill is more likely.
