            Bug ID: 1240487
           Summary: erl segfault on fedora-23-i686 (autoconf testsuite)
           Product: Fedora
           Version: rawhide
         Component: erlang
          Assignee: lemenkov(a)gmail.com

We observe autoconf FTBFS on rawhide (testsuite failures).  One of the
testsuite failures is related to Erlang & autoconf, but it appears only on
i686.  I tried to cut related testcase out into segfault-i686.tar.gz
reproducer:

  $ tar -xf segfault-i686.tar.gz
  $ cd segfault-i686
  $ make && make run
  erlc -b beam my_testsuite.erl
  cd lib && ./compile
  erl -pa ./lib -s my_testsuite test
  Erlang/OTP 17 [erts-6.3] [source] [smp:4:4] [async-threads:10] [hipe]
  [kernel-poll:false]

  Eshell V6.3  (abort with ^G)
  1>   All 3 tests passed.
  Makefile:6: recipe for target 'run' failed
  make: *** [run] Segmentation fault (core dumped)

The segfault ^^ breaks autoconf testsuite, but I'm not able to diagnose
properly.  Any help appreciated, let me know if you need some other info.
