On an Intel amd64 machine with the latest snapshot (Jul 24th), net/unison
dies for me on startup with the culprit being `caml_startup__code_begin`. I
guess this is because O'Caml hasn't been updated sufficiently for IBT? Here's
what I see:
$ unison -h
fish: Job 1, 'unison -h' terminated by signal SIGILL (Illegal instruction)
$ gdb unison

(gdb) run
Starting program: /usr/local/bin/unison
Error while reading shared library symbols:
Dwarf Error: wrong version in compilation unit header (is 4, should be 2) [in module /usr/libexec/ld.so]
Program received signal SIGILL, Illegal instruction.
0x00000d8d44d79a30 in caml_startup__code_begin () from /usr/local/bin/unison
However, Unison on this same snapshot works fine on an AMD amd64
machine. AFAIK the main difference between the two is the lack of IBT
support on the AMD machine.
