Modified Files: src/sys/arch/amd64/amd64: db_interface.c src/sys/arch/i386/i386: db_interface.c Log Message: Fix NULL pointer dereference via ddb_regs ddb_regs can be *ddb_regp (see db_machdep.h) so ddb_regp should be NULL-ed after dereference to ddb_regs. Also dbreg should be restored to ddb_regp because ddb_regp can be changed by db_mach_cpu during db_trap.
