I have just learned about the "leaks" unix utility for detecting
memory leaks but I'm not unix savvy enough to understand a point

"If the MallocStackLogging environment variable was set when the
application was launched, leaks also displays a stack trace
describing where the buffer was allocated."
Can anyone who uses this utility tell me how to set the this
environment variable? I'm thinking it's possible this must be set
via GDB, otherwise I'm not sure where it could get a stack trace
from. Thank you for helping.
Environment variables can be set in your shell; the syntax depends on
which shell you use. You can also set environment variables when you
launch the app inside gdb:
(gdb) set env MallocStackLogging 1
(gdb) run
For more information about malloc stack logging, read this:
