Note that this particular initialization doesn't do anything. Static variables are automatically initialized to 0.

Thanks! --- I overlooked that one --- then the rather high value of hottop (600037897) I encountered was indeed only cause by incrementing it "unboundedly" rather than an "unexpected" initialization ...

Also note that in the HEAD branch, hottop is initialized to MAXHOT (causing a propagation conflict).

I indeed did not check the HEAD branch --- I cannot tell which is supposed to be the "correct" initial value, 0 or MAXHOT --- maybe Martin can help ... Stefan

Modified Files: Tag: Feb2010 mal_interpreter.mx Log Message:

make sure we initialize the static global variable hottop at least once; I hope, 0 is the correct initial value.
