Hi, all:

Recently I have been very interested in th= is=20 stuff, by using gdb 's target remote

I can connect to gdb_stub successfully. Now I could make gdb=20 to set breakpoint, continue,

ctrl+c to come back, k to quit to normal and connect it again. But it= 's not=20 perfect, it always

crash occasionally when I press 's' to step into, or p= ress=20 'n' to pass a fucntion.

I don't know it's or not gdb_stub's bug,&n= bsp;=20 right now I prone to suspect 'M' which command

inserts a int3'0xcc' may have some imperfect. if so, how to fix it, h= ope=20 somebody who is

proficient at it or have met the same problem can help me, thanks a=20 lot!
