If make gdbserver use software breakpoint on x86, th= is > issue can be produced. I think you mean hardware single stepping, not hardware breakpoint. GDB us= es software breakpoints for x86 as well as ARM. But GDB uses hardware single stepping for x86, and software single stepping for ARM (meaning it inserts a breakpoint at the next instruction(s) and resumes when it wants to single step). --=20 You are receiving this mail because: You are on the CC list for the bug.=
