I just installed MMD 4.4 using the installer, and now when I invoke multimarkdown, I get Illegal instruction: 4 as the result. The console messages show this:

11/25/13 9:28:45.228 PM ReportCrash: Failed to create CSSymbolicatorRef for bash[18994]
11/25/13 9:28:45.338 PM ReportCrash: Failed to create dSYM-less CSSymbolicatorRef for bash[18994]
11/25/13 9:28:45.658 PM ReportCrash: Saved crash report for bash[18994] version ??? (???) to /Users/rob/Library/Logs/DiagnosticReports/bash_2013-11-25-212845_joebob.crash

The contents of the crash report are enclosed.

I tried removing the binaries in /usr/local/bin and running the installer again, but it didn't make a difference.

Any advice would be greatly appreciated.

    Thanks for writing in.

    The binary version of MMD included in the installer was compiled for modern hardware/software machines. It takes extra steps to compile for older versions of the Mac OS, or for older machines (e.g. 32-bit machines or PPC).

    I'll try to work out a workflow that allows a single binary to run across more machines, but the surefire way to run on older versions of the OS or older hardware, is to compile MMD for yourself (either by downloading source from github, or through something like homebrew). It should compile for any version of Mac OS (10+), and on any hardware. But the individual binaries won't necessarily run across all versions of hardware/software.

    Hope this helps!

    The 4.4.2 update solved the problem.

    Thank you very much.
