The libsmi parser memory faults when parsing mibs/ietf/DOT12-RPTR-MIB.
Repeat by running
smilint mibs/ietf/DOT12-RPTR-MIB
after installing libsmi. This happened to me under RedHat 9 (gcc
3.2.2/x86) and RedHat 7.3 (gcc 2.96/x86).
The parser usually runs off the rails thus:
$ gdb /usr/local/bin/smilint
[stuff omitted]
(gdb) run mibs/ietf/DOT12-RPTR-MIB
Starting program: /usr/local/bin/smilint mibs/ietf/DOT12-RPTR-MIB

mibs/ietf/DOT12-RPTR-MIB:151: warning: use Integer32 instead of INTEGER

Running with ElectricFence and EF_PROTECT_BELOW on turns up a problem,
if that helps. I can provide details if that would help.
