I am getting a segfault in master when building:
CCLD temacs
/bin/mkdir -p ../etc
: paxctl -r temacs
: setfattr -n user.pax.flags -v er temacs
make -C ../lisp update-subdirs

done;

The responsible commit (according to git bisect) is:
commit b74db6347cf5cac1ebd4c604fd5691c588fd8e32

Backtrace after malloc arena is corrupted
Without this change, if the malloc arena is corrupted and then
'backtrace' is called, the backtrace can crash because 'backtrace'
calls 'malloc'. For more, please see:
https://sourceware.org/ml/libc-alpha/2015-02/msg00678.html
* emacs.c (main): Initialize tables used by 'backtrace'.
* sysdep.c (emacs_backtrace): Document the newly used part of the API.

This corresponds well with the location of the crash:
Program received signal SIGSEGV, Segmentation fault.
