Make sure you use synchronous mode when stepping through your program.
I suspect your random results are caused by Xlib buffering.

Anyway, the asin error is probably a bug in your server.  Some of the
arc and wide line end cap code uses the asin function.  By default,
asin prints the error you mention if it is called with an invalid
argument.
