Summary: Segfault in snmpd apparantly caused by non
initialised shared library BSS
Description:
net-snmpd 5.1.2 built with buildroot sometimes segfaults on startup.
Once this occurs it is 100% reproducable until reboot...
Prelimery investigation points to uClibc shared library support (but I may
be wrong...)
Segfault occurs because external_signal_scheduled[] and
external_signal_handler[] defined in agents/agent_registry.c and compiled
to libnetsnmpagent.so are not initialised but the code assumes they are
zero filled on startup.
