It could be, but its unlikely.

The easiest way to find out would be to:
1. compile PostGIS with the -g option (to get debug information in it)
2. make sure valgrind is installed on your system
3. run the postmaster with valgrind (ie. "valgrind postmaster -D ...")
4. run your query
5. see where valgrind says it died.
