Comment 9 Alec Leamas 2015-07-30 16:22:50 UTC 
Hi!

Sorry for late reply....

This boils down to a bug  or limitation in the select(2) call: the FD_ macros behaviour is undefined if the file descriptor is > 1024. Since linux supports such descriptors, we have a problem. I have been able to reproduce the same type of crash on lircd.

The correct solution seem to be to use poll(2) instead, which doesn't have this limitation. However, we are now in the process of releasing 0.9.3, and this change is too big to be done before that.
