[BUG} gdb disassembly-flavor affecting display of call stack.
by Nikolay Borisov
Hello,
I've observed the following rather peculiar behavior of crash 7.1.3 (gdb
7.6).

How come setting the disassembly flavor (which should be just a
presentation aid) affects the displaying of the callstack? It took me a
while to correlate this behavior. It's also strange that this doesn't
happen on all processes on a vmcore file but only on some, so far I
haven't been able to find any clues as to which processes this applies to.
Regards,
Nikolay
