    I had crashes due to corrupted pointers and put a hardware watchpoint at the structure in question to figure out who was changing it. It triggered at the code in question, and removing it (by reverting the patch) fixed the issue.

    Hi, I believe you need to use Perl callbacks, ie. something like my $cb = sub { print "foo\n"; }; $sess->get(..., $cb); while (1) { SNMP::MainLoop(); } Just print $sess->get(...) won't use a callback, since it's synchronous.

The bug is clear enough when you look at the code, although of course a regression test would be nice to have.
