I have found a repeatable crash with 7.8.0 used on a dual G5 Mac running OSX 10.4 / X11:
Upon issuing the command:
mged> B -A material_id 5
-or-
mged> B -A material_id "5"
I recieve an error dialog box reading:
Bad pointer xbfffd620: s/b bu_attribute_value_set(x41765321), was Unknown Magic(x2f456e0), file avs.c, line 255
followed by a crash to prompt.
Upon adding "-o" to the command:
mged> B -A -o material_id 5
-or-
mged> B -A -o material_id "5"
I simply crash to prompt, no error dialog box.

Should be fixed in next release. See Tracker Item #29076

This was fixed in the 7.12.0 release by JRA.
( doesn't really matter but 29076 looks like an invalid tracker item )
