/** @file vgsuppression.c
|
|
** dummy executable to generate _valgrind suppressions_.
|
|
** When running code under `valgrind` to detect memory leaks, typically a well known set
|
|
** of false alarms will be reported. The reason is that some facilities, either implemented
|
|
** by our own or from third party libraries, just choose never to free some working buffers.
|
|
** To deal with this well known issue, `valgrind` allows to be "primed" with a specifically
|
|
** crafted executable, which deliberately triggers just these false memory leak alarms.
