Hi, all: Recently I have been very interested in this stuff, by using gdb 's target remote I can connect to gdb_stub successfully. Now I could make gdb to set breakpoint, continue, ctrl+c to come back, k to quit to normal and connect it again. But it's not perfect, it always crash occasionally when I press 's' to step into, or press 'n' to pass a fucntion. I don't know it's or not gdb_stub's bug, right now I prone to suspect 'M' which command inserts a int3'0xcc' may have some imperfect. if so, how to fix it, hope somebody who is proficient at it or have met the same problem can help me, thanks a lot! tpopusher _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
