[libsmi] smidump segmentation fault

25 Apr 2005


      Setup:
Redhat Linux 9 x86
libsmi 0.4.3
gcc 3.2.2
To trigger problem:
    smidump --format=mosy CISCO-IETF-FRR-CAPABILITY.my
File CISCO-IETF-FRR-CAPABILITY.my attached.  Cisco does not provide a 
copy of the CISCO-IETF-FRR-MIB referenced in 
CISCO-IETF-FRR-CAPABILITY.my.  Segmentation fault is a bit cryptic as a 
diagnostic, though :-).
I had to compile without -O2 in order to get a reasonable looking stack 
trace, which is as follows:
Program received signal SIGSEGV, Segmentation fault.
