Perhaps you could add a sig handler to your code. Something like the sig handler here:
#! use Carp; use strict; use warnings; $SIG{INT}=\&CtrlC; sub CtrlC { $SIG{INT}=\&CtrlC; Carp::carp('Caught a CTRL/C'); }; sub mySub { for (1..10) { <STDIN>; }; }; for (1..10) { <STDIN>; }; mySub(); exit;
When it hangs again, just give it a ctrl/c and see where it carps from.

    vroom: That was quite helpful. However, in Perl 5.8.8 in Windows environment, any attempt to override SIGINT or SIGBREAK will be ignored. Furthermore, my program communicates with another interface, which is old, and must be installed on Perl 5.8.8 to work. I can't upgrade my Perl version to 5.10.0.

    Anyway, the whole program is actually running within a huge Event-1.10 loop. I've setup a test environment with Perl 5.10.0 installed to experiment with your suggestion, and was letdown when Carp merely reports that CTRL/C was caught at this line:
    Event::loop;

[zentara]: Strange, on clicking a link in a node, I am taken to that node, but my votes and login are lost. Should I post a Permonks Discussion?
[choroba]: that just means someone used a wrong link format

[Corion]: zentara: Most likely they used something like [http://www. perlmonks.org/? node=123456] instead of [id://123456], which uses whatever domain you're visiting from
