I looked around a bit last night and found some relevant discussions:
http://gcc.gnu.org/ml/gcc/2002-07/msg01417.html
http://www.gelato.unsw.edu.au/archives/linux-ia64/0109/2178.html
I also came across this, which suggests that adding a dummy setjmp
before the getcontext call might help:
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/144939
So I tried adding a dummy setjmp call (which isn't actually executed)
right before getcontext in continuations.c, and that does fix the
illegal instruction when executing (call/cc (lambda (c) (c #t))).
However, without having a better understanding about what's actually
happening, I'm not inclined to treat this as a correct solution yet.
Can anyone else comment more conclusively?
Thanks
