Re: Non-deterministic behaviour with simple array initialization

... which means that at some point suddenly @e is not undef anymore.
Not really :)

@x{1..2**31} = (); \%x
Range iterator outside integer range at - line 1.

On win32, activeperl5.8.6 and strawberryperl5.10, I get no error messages, the script just keeps running (i kill after 10min)

It has something to do with c compilers, int size, malloc ... probably deterministic, but thats range operator abuse :)

Hi anonymous monk, I don't get error messages on the other VM either, that's what makes this problem very strange to me ... The range iterator message is one of the rare ones :) the illegal division or the sudden execution of the print statement after the n'th while loop is much more 'likely'. Do you have a hint for me how I could narrow it further down? It's the default SuSE perl distribution, no custom stuff. Dop you think I should try to tackle it with valgrind or something? Thanks, Thomas	[reply]
