Description

=begin
When calling resume such as:

f = Fiber.new { puts "foo" }
f.resume

I'm getting the following segfault:

This doesn't appear to be a problem on 1.9.3-head and may be related to Issue #4827.

I think this is similar to #4827 too.

r31954 is fix for this, but it cannot backport straightly because of r27635.

A patch for branch_1_9_2 is as follows

Index: cont.c

--- cont.c (revision 32347)
+++ cont.c (working copy)
@@ -882,6 +882,7 @@
/* no need to allocate vm stack */
fib = fiber_t_alloc(fiber_alloc(rb_cFiber));
fib->cont.type = ROOT_FIBER_CONTEXT;

  • fib->status = RUNNING;
    fib->prev_fiber = fib->next_fiber = fib;

    return fib;

Unfortunately, I'm still getting the bus error after applying that patch.

Updated by dweinand (Dan Weinand) over 12 years ago

Actually, this looks like it could be related to #4651. I'm going to check out that commit, and see if I can get things working.

Updated by dweinand (Dan Weinand) over 12 years ago

=begin
Yes! I can confirm that this is the same issue as #4651 and r32201 fixes it.

The commit applies cleanly to 1.9.2. Can we get it backported?
=end

Updated by sikachu (Prem Sichanugrist) over 12 years ago

Yes, I agree on backporting #4651 into 1.9.2 branch. It's impossible now for me to develop stuff using Lion, as I can't even run Rails's Action Pack test cleanly >_<

Thank you so much.

I'm also getting this segfault any time I call Fiber#resume. Please backport asap. Thanks.

I built Ruby-1.9.2-p290 patched with this commit: https://github.com/ruby/ruby/commit/be953b4d1ce3f0dfc7f24c84ec7a51e027102557

and now I get the following:
