List of ROBOTC Bugs

If two user defined functions occur on the same line (i.e. are compared in an if statement), they will always return the same value.
If the NXT brick crashes while connected to the computer, RobotC crashes as well.
Strings have a maximum length of 19 chars (at least with strlen).
SendStringAdv hangs if no receiver is present when the function is called, i.e., no re-sending, so if the receiver isn't actively listening, the sender is stuck
RC_atoi doesn't work for negative numbers
If you #include "a.h", and "b.h", but b.h includes a.h, you get an error

Missing features:

Matching braces in the editor
Automatically call InitRS485() the first time a communication function is called
strlen
