[Freeipmi-devel] ipmi-sensors crash

[Dave Love]

I got a segv trying to run ipmi-sensors (1.3.4).  It may be relevant
that the system is somewhat unusual -- four (Bull) servers glued
together to make a large SMP box.

I don't have time to debug it properly, but here's a backtrace, although
it may be junk, given the top of the stack.  I can send specific info
that might be useful.  The --debug output is 120k compressed, so I
haven't attached it.
