After finally figuring out how to provide gdb with binaries that it can use (#574284), here's a backtrace.

So, that SmiHandle pointer must have been initialized before one may use the function. So, let's look for smiInit()... It should have been called in epan/oids.c:register_mibs() which is called by epan/oids.c:oids_init(). oids_init() is called by epan/prefs.c:read_prefs() but only if prefs.load_smi_modules is set. In my case, oids_init() is not called. HTH, -Hilko -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
