Hi,
When looking through the gcov results I see in a few cases
strange execution counts for signal declarations. The two
most prominent examples are appended.
I'd expect that the execution count is 1, because the signal
is initialized and that happens exactly once at startup.
But how comes that a single signal is 'executed' thousands of times ?
Code was compiled without -O options, thus without optimization.
Any hint very appreciated.
With best regards, Walter
