Debugging Dynamic Memory Usage Errors Using HP WDB

NOTE: If the application invokes calls such as system(3s), and popen(), which invoke

a new shell, librtc.[sl|so] must not be loaded to the invoked shell. You must use

LD_PRELOAD_ONCE, instead of LD_PRELOAD, to exclusively load thelibrtc.[sl|so] file

to the calling process only.

Following is the syntax for using LD_PRELOAD_ONCE:

LD_PRELOAD_ONCE= /opt/langtools/lib/librtc.sl

Example 15 (page 61) illustrates the batch mode debugging of the memtest.c program. The

debugging results are stored in memtest.8494.mem, memtest.8494.heap, and

memtest.8494.leak.
