Problems with GC.. again

Hi.

Again, I ran into some kind of wrongly garbage collected object, but
can’t determine exactly which one.

Sources is at:
http://files.whitequark.ru/rlua.tgz

Try:
ruby1.9 extconf.rb
make
ruby1.9 test.rb

A segfault!

WBR, Peter Z.

P. S. Can someone show me how does addr2line work? It doesn’t show
anything other than “??” with /usr/bin/ruby1.9,
/usr/lib/libruby1.9.so, ./rlua.so… May this be because Debian
binaries are stripped?

Why do you use such old, unreleased revision?

It’s latest 1.9 packaged in Debian.

sigh

Debian maintainers really seem to have it out for ruby… yet another
example.

Well, your code doesn’t segfault with 1.9.1p0 anyway.

$ ./ruby ext/rlua/test.rb
