condition.cpp: condition_impl::notify_one swallows errors from WaitForSingleObject

[anonymous]

condition_impl::notify_one silently swallows errors from WaitForSingleObject. The author got the asserts correct, but took no action on failures.

My apologies for throwing a runtime_error. I'm not familiar enogh with boost to know what should be thrown. I also suspect the code should throw earlier than before function exit.

throw std::runtime_error("Failed to wait on mutex");

if(wait2 != WAIT_OBJECT_0)

throw std::runtime_error("Failed to wait on gate");

Sorry, I don't see any file libs/thread/src/condition.cpp. Moved to support request until concerned file clarified.

Closed as it seems this doesn't corresponds to the current Boost.Thread implementation.
