well it will show up calls to mmap and brk made by the c library, however for
tracking memory usage better ltrace would probably be a better option in this
case.

However strace will show memory exhaustion anyway, and it is one of the best
debuging tools around.

As has been pointed out in later messages the gnu time command will show qute
a few interesting statistics about memory usage of a process, also useful.

There are other techniues one can turn to, including malloc debugging
libraries and putting other forms of profiling before various library/system
calls in your program.
