it occasionally crashes, but i dun know where to start.
it occured when freelist dereferences invalid freelist->as.free.next address.
because the process accidentally terminated during collecting stack dump, you 'll need to wait for more crashes....

Hi,

2010/7/12 jojelino lastname [e-mail]:

ruby -v: ruby 1.9.3dev (2010-06-27 trunk 28448) [i386-mingw32]

It's slightly old. Some GC bug was fixed recently at r28472
(2010-06-29). Could you try the latest trunk?

OTOH, ruby_1_9_2 had been alread fixed at r28191 (2010-06-06).
See [ruby-core:30921] in detail.
