Memory Leak Detection

One of the most powerful tools that is bundled with Oracle Solaris Studio is Discover, which is a

memory error discovery tool for detecting memory access errors and leaks.

To use Discoverer, the following steps must be performed:

• As a prerequisite, the code must be compiled with Oracle Solaris Studio compiler optimization flags

-xO[n]:

cc -g -xO2 test.c

•

Instrumentation codes need to be added to the binary:

discover -w text a.out

Note: Discover automatically adds instrumentation to shared libraries when they are opened.

• Once instrumentation is added, the instrumented binary can be run and the usual testing, including

stress tests, can be continued.

• The tool will track all the memory leaks during the runs, which can be viewed through the report

generated by the tool.
