[New-bugs-announce] [issue7494] _lsprof (cProfile): Profiler.clear() keeps references to detroyed nodes

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at haypocalc.com>:

clearEntries() delete all nodes of the profiler tree, but 
currentProfilerContext keeps a reference to a tree node 
(currentProfilerContext->previous->header attribute).

The patch fixes clearEntries() to delete all references (destroy 
currentProfilerContext and set it to NULL).
