I wrote my first extension!
The functions work fine… except when I’m making multiple calls in a
loop.
Then, it segfaults. I wrote some more code in my extension to output
equivalent c code to do the same job - even across my multiple data, and
it
does fine. So I’m thinking either there’s some weirdness I don’t know
about, I’m accidentally clobbering some data, or there’s a bug in ruby
that
I stumbled across (ruby 1.8.4 (2005-12-24) [powerpc-darwin8.4.0]) - my
question is, how do I figure this out? Right now, my plan is to add
fprintf(stderr, “%s [%d]\n”, FILE, LINE); to the end of every
line
in my c extension and see what gets dumped… but is there an easier
way?
Thanks,
