Hi, I managed to reproduce the error in qemu emulated virtual machine, which lacks the support of hardware watch point. The failed test case breakpoint-in-ro-region.exp attempts to set the memory region of the debugged program read-only and force the use of hard breakpoint. The test bench itself takes the case where breakpoint is not supported into account, but failed to notice the slight difference of the output when using gdbserver. That's why the test runs well with normal gdb but fails with gdb server. The attached patch can fix the above issue. However, I have no idea why on the buildd environment, hardware breakpoints cannot be set by gdb. Cheers, Miao Wang
