If not, I'll take a look. 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?
