#1353: Segfault occurs when invoked the Module#{const_set, const_get} within some
threads.

Type: defect | Status: new
Priority: blocker | Milestone:
Component: MacRuby | Keywords:
----------------------------------+-----------------------------------------
Maybe, I guess that this problem is similar with #1352.
Test Script:
{{{
#!ruby
m = Module.new
th = Thread.new {
1000.times do |i|
m.const_set("M1#{i}", i)
end
}
1000.times do |i|
begin
m.const_get("M1#{i}")
rescue
end
end
th.join
}}}
BackTrace:
{{{
