x86 done...

Seems to work on ppc, hansmi has already marked it stable.

Created attachment 88553 [details]
dfbsummon output

I tried running dfbsummon. It opens a blue window for a very short instant and then closes immediately again. Attached is the output, showing that it crashes because of a floating point exception (signal 8) caused by a division through zero. I don't think that's intended, is it? ;)

sorry, i meant to include a gdb backtrace in my last comment:

Program received signal SIGFPE, Arithmetic exception.

Chuck Norris can divide by zero, why can't you?

*grin*

[Comment 6 Simon Stelling (RETIRED) 2006-10-23 04:11:20 UTC]

I marked 0.9.25.1 stable instead as it doesn't have the issue mentioned in comment 3 and even has amd64 assembler.
