R12 emulator crashes with zero-length port_control binary
Wed May 26 02:56:30 CEST 2010
If a linked-in driver returns 0 to a port_control call and
PORT_CONTROL_FLAG_BINARY is set then the beam emulator will probably
crash or otherwise misbehave.
Attached is a patch for those who are stuck on R12 and might get
bitten by this. Tested on R12B-3, applies also to R12B-5.
It's already fixed (in a different way) in R13+
