Public bug reported:

In the epicsThreadHookAdd(EPICS_THREAD_HOOK_ROUTINE hook) function in
modules/libcom/src/osi/os/default/osdThreadHooks.c memory is allocated
for pHook. Then a mutex is calimed and if successful the hook is added
to a list of hook. If th emutex fails however the memory for the pHook
is not freed.

This is reported as an error by the Codacy static code analysis.
