Hi Mike,
We have been struggling for some time with random crashes that seemed
somehow to be connected with our use of coroutines (which is quite
intensive), and at last I managed to distill it down to the following test
case:
local n = 0
local function nxt()
n = n + 1
return n < 100000 and (n % 100 == 0 and 2 or 1) or nil
end
local f = {
coroutine.wrap(function() while true do coroutine.yield()
end end),
function() end,
}
for i in nxt do
f[i]()
end
Just running this chunk in either Windows or Linux produces a segfault.
Switching off JIT (-joff) makes the problem go away so it has something to
do with compiled code.
I hope you can quickly find the cause as this is quite central to our
application.
Janis
