P. S. Notice, that we get this only on x86_64.
Both i386 and ppc build fine on 10.6.

The oldest version of macOS that is "officially" supported by Mercury is 10.9. That said, Mercury definitely worked with 10.6 on x86_64 when that version of macOS was originally released and we haven't done anything since then that would prevent it from working (in principle).

As a starting point for investigating this, I would try the following:

  1. Try bumping up the stack size, e.g. (using ulimit -s), and see if that resolves the issue. (IIRC, stack exhaustion when doing --generate-dependencies step has been a problem in the past.)

  2. Try disabling optimisations in the C compiler, e.g. pass -O0 to clang. You can do this by creating a file named Mmake.params at the top-level of the Mercury source tree containing the following:

    EXTRA_CFLAGS = -O0

    This should give us a clue as to whether the issue is being caused by a misbehaving C compiler optimisation.
