#620: Yielding a block inside a loop in a thread crashes the VM ---------------------------------+------------------------------------------ Reporter: honglilai@… | Owner: lsansonetti@… Type: defect | Status: new Priority: blocker | Milestone: Component: MacRuby | Keywords: ---------------------------------+------------------------------------------ Yielding a block inside a loop directly in the Thread block results in a VM crash: {{{ Assertion failed: ((b->flags & flags) == flags), function rb_vm_prepare_block, file dispatcher.cpp, line 1737. Abort trap }}} Interestingly, the problem doesn't occur of the loop is wrapped inside a function. Reproduce with: {{{ require 'thread' def do_yield yield end # This doesn't crash. Thread.new do do_yield do end do_yield do end do_yield do end end.join # This doesn't crash either. def do_yield_loop_in_function while true do_yield do end end end Thread.new do do_yield_loop_in_function end.join # This crashes.

#446: Dispatch::TIME_FOREVER too big for signed long long -------------------------------+-------------------------------------------- Reporter: niklas@… | Owner: lsansonetti@… Type: defect | Status: new Priority: minor | Milestone: MacRuby 0.5 Component: MacRuby | Keywords: gcd semaphore long long TIME_FOREVER -------------------------------+-------------------------------------------- Dispatch::TIME_FOREVER is 18446744073709551615 so it fits into a unsigned long long. When you call "wait" with TIME_FOREVER on a semaphore the function in gcd.h (l. 826) uses NUM2LL(time) to convert the time in to a signed long long which leads to {{{ core:in `wait:': bignum too big to convert into `long long' (RangeError) from untitled:1:in `<main>' }}} I've seen this in MacRuby 0.5 beta 2 -- Ticket URL: <http://www.macruby.org/trac/ticket/446> MacRuby <http://macruby.org/>
