14.10.10.6 Example for heap profiling
This example shows how to use this feature on HP-UX 11.x:
1. If the linker version is earlier than B.11.19, link with /opt/langtools/lib/
pa20_ 64/librtc.sl for PA-64 programs. For a 32-bit program, you must link
with /opt/langtools/lib/librtc.sl.
If the dynamic linker version is B.11.19 or later, skip this step because WDB
automatically loads the librtc.sl library.
2. Turn on profiling with the set heap-check on command:
(gdb) set heap-check on
3. Set a breakpoint:
(gdb) b myfunction
