I can't bootstrap emacs on master branch, atm : temacs dumps core.
The backtrace is below.

This specific error (i.e. SIGSEGV in temacs) was introduced by the
commit below. Before that commit, however, "make bootstrap" wouldn't
work either (namely it was not able to link temacs -- see after the
backtrace if that's of any interest).

    Don't use OUTER_TO_INNER macros for plain X and lucid.
    
    * xmenu.c (create_and_show_popup_menu): Call XTranslateCoordinates,
    dont use OUTER_TO_INNER macros.
    (x_menu_show): Call x_real_pos_and_offsets, don't use
    OUTER_TO_INNER macros.

Now the gdb output with backtrace (note that I disabled the loading of
src/.gdbinit because of errors):

FTR, here's what the error is when the parent of

(that's in french, but I assume you can guess the meaning -- and I can
reproduce in english if necessary).

Thanks, I installed a (slightly different) patch as commit 
cbc9d8d4269f2cca7950060b5e37747b27dac1de and am marking Emacs Bug#19959 
as fixed.  I also filed a bug report with the glibc folks (glibc bug 18084).
