I've poked through ptrace.S, but it's been a long time since I did any assembler, and when I did, it was 6502. . . N -- Internet connection, $19.95 a month. Computer, $799.95. Modem, $149.95.

in the man pge PT_STEP The traced process is single stepped one instruction. The addr and data fields are not used. this is a lie. you must feed ptrace() a valid value for addr, just like PT_CONTINUE Fix: let users know that the addr is required How-To-Repeat: try and ptrace(PT_STEP, pid, 0, 0) something ;)
