--- Comment #3 from Siddhesh Poyarekar <siddhesh at sourceware dot org> ---
tr_break has been removed in 2.34.

    mtrace: Deprecate mallwatch and tr_break

    The variable and function pair appear to provide a way for users to
    set conditional breakpoints in mtrace when a specific address is
    returned by the allocator.  This can be achieved by using conditional
    breakpoints in gdb so it is redundant.  There is no documentation of
    this interface in the manual either, so it appears to have been a hack
    that got added to debug malloc.  Deprecate these symbols and do not
    call tr_break anymore.
