I have now boiled it down to the mis-compilation of one file in t1lib5, 
lib/type1/objects.c. If this is compiled with a low optimization level 
such as -O1, xdvi works, if it is compiled with the standard -O2, 
segmentation fault. This is very weird, because this is C code, not C++. 
Plus, the crash doesn't even happen in objects.c, but in some other 
modules. I haven't seen anything about this in google either. Some more 
bug hunting in order, I guess.
