kbyanc 2004-12-08 19:03:55 UTC FreeBSD src repository Modified files: sys/i386/i386 vm_machdep.c Log: If the parent process has the trap bit set (i.e. a debugger had single stepped the process to the system call), we need to clear the trap flag from the new frame unless the debugger had set PF_FORK on the parent. Otherwise, the child will receive a (likely unexpected) SIGTRAP when it executes the first instruction after returning to userland.
