#2557 application using libnetsnmpagent.so is crashing at start
Application (asterisk in this case) using the libnetsnmpagent library is crashing at the start. Backtrace shows that crash happens inside the libnetsnmpagent library, so I'm reporting it here, not in asterisk (this is actually similar to the bug #2073, that also was causing asterisk to crash, and it was fixed here).

Cheesus. Any chance I could fix the mess above ?
here's a backtrace anyway in human-readable form:
A can't see how it is possible to crash at that line.
How did asterisk and net-snmp get into your system? ports collection? pkg? Did you compile them yourself?
My immediate suspicion would be a 32/64 bit mismatch
