--- Comment #4 from Jean-Michaël Celerier <jeanmichael.celerier at gmail dot com> ---
I get a similar crash with the following symbol :

_ZSt4moveIRZN5coppa8oscquery15WebSocketClientC1INS1_12RemoteDevice8m_clientMUlDpOT_E_EEEOT_EUlSt8weak_ptrIvEE_EONSt16remove_referenceIS9_E4typeESA_

The code is compiled with clang-3.6, and both gdb-7.9, lldb-3.6, and
c++filt-2.25.0 choke on the symbol.

When debugging c++filt with gdb, it seems like the infinite recursion is in
libbfd.so.

    Fix breakpoint thread condition missing with mi and a pending breakpoint.

    When setting a pending breakpoint with a thread condition while using
    the mi interface, the thread condition would be lost by gdb when the
breakpoint
    was resolved.

    This patch fixes this behavior by setting the thread condition properly in
the
    mi case.

    Also, this patch modifies the mi-pending test case to test for this issue
and
    removes some unneeded code in the testcase and dependency on stdio.

    gdb/Changelog:
        PR breakpoints/16466
        * breakpoint.c (create_breakpoint): Set thread on breakpoint struct.

    gdb/testsuite/ChangeLog:
        PR breakpoints/16466
        * gdb.mi/Makefile.in: Add mi-pendshr2.sl to cleanup.
        * gdb.mi/mi-pending.c (thread_func): New function.
        (int main): Add threading support required.
        * gdb.mi/mi-pending.exp: Add tests for this issue.
        * gdb.mi/mi-pendshr.c (pendfunc1): Remove stdio dependency.
        (pendfunc2): Remove stdio dependency.
        * gdb.mi/mi-pendshr2.c: New file.
