            Bug ID: 17167
           Summary: addrmap.c:125: internal-error:
                    addrmap_fixed_set_empty: fixed addrmaps can't be
                    changed
           Product: gdb
           Version: 7.7
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdb
          Assignee: unassigned at sourceware dot org

When dynamically loading shared libs, GDB crashes with

addrmap.c:125: internal-error: addrmap_fixed_set_empty: fixed addrmaps can't be
changed

Environment Information
------------------------
OS SLES10SP3-3 configured as x86_64-unknown-linux-gnu
Crashing Versions 7.7.1, 7.6.1, 7.5.1
Working Versions 7.3.1, 7.2, 7.1, 6.8 although we were having problems with
these so we upgraded steadily.
GDB is launched by the process to be debugged and attached to it like so

gdb /dev/null --batch --init-command=.gdbinit --command=.gdbpostinit pid

GDB Compiled with GCC 4.8.1, 4.2.2
Process under debug compiled with GCC 4.2.2 & 4.5.1, or ICC 14. Typically
compiled with -O0 -g or -O0 -ggdb

Any advice on what part I can localize the root cause around?

Thanks,
Greg

PS: This does not work on any version
