my program doesn't call anything like readline

Oops--sorry. It indeed does call a readline. However, that problem notwithstanding, the debugger continues to behave oddly. After the debugger loads, my program takes about 10 seconds before anything appears to happen with it. Then, stepping in/out/over is unreliable, with the "program counter" (the red arrow that indicates which line is about to be executed) pointing to the wrong line. Jerry
