it seems its because of exchange_fiber function content (doesn't crash if
exchange_fiber() is empty). See attached file for lua code. Problem reproduced
on ubuntu (salentos) 32 bit under vmware workstation 9.
function exchange_fiber(fixChan)
print("exchange_fiber");
while true do
local msg = fixChan:get();
end
end
function libfin_test()
local boxChan = box.ipc.channel();
local orderGen = box.fiber.create(ordergen_fiber);
local fc1 = LibFin.FixChannel:new(boxChan);
box.fiber.resume(orderGen, fc1);
local exchange = box.fiber.create(exchange_fiber);
local fc2 = LibFin.FixChannel:new(boxChan);
box.fiber.resume(exchange, fc2);
end
