             Bug #: 15099
           Summary: gdb fails to insert breakpoint in qemu-kvm, when
                    enable PIE support
           Product: gdb
           Version: 7.5
            Status: NEW
          Severity: normal
          Priority: P2
         Component: breakpoints
        AssignedTo: unassigned@sourceware.org
        ReportedBy: powernp4gs3@yahoo.com.cn
    Classification: Unclassified


qemu-kvm version: 1.2.0
gcc version: gcc (Ubuntu/Linaro 4.7.2-2ubuntu1) 4.7.2
gdb version: GNU gdb (GDB) 7.5-ubuntu
linux distribution: linuxmint 14

How to Reproduce:
(1) Download qemu-kvm source code:
http://jaist.dl.sourceforge.net/project/kvm/qemu-kvm/1.2.0/qemu-kvm-1.2.0.tar.gz
(2) configure qemu-kvm with this options (defaults, enable PIE support):
# ./configure --enable-debug --enable-kvm
# make
# gdb x86_64-softmmu/qemu-system-x86_64
then set args, run, but throw this:
Warning:
Cannot insert breakpoint -1.
Error accessing memory address 0x3849c0: Input/output error.

But when configure with --disable-pie, no problem:
# ./configure --enable-debug --enable-kvm --disable-pie

Can you try a newer gdb?
This sounds like PR 13987, recently fixed.

I try the snapshot, gdb-weekly-CVS-7.5.50.20130205, no problems, the patches
fixed the PIE bug.
