MMD6 Pointer Error

I started seeing this error sometimes when compiling using Scrivener, which by itself speaks of missing access rights. MMD 6.0.0 produces the following error message.

multimarkdown(2683,0x7fff789e2000) malloc: *** error for object 0x1010101a4: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

    Can you send me the file that does this? I have been unable to trigger a memory error in quite a while, including almost 300 million different tests using a "fuzzer" that adds noise to test files to try and find new edge cases. If indeed this is a new one, then kudos to you. ;)

    As for Scrivener, I can't help you there -- Scrivener support has to come from them. Obviously problems with MMD itself are mine to help with.

    Hey Fletcher,

    sure I need to reproduce it but that should be do'able since the error occurred repeatedly. Do you have an email address or some other way to share it with you? Given that the file contains my writing and personal information, I trust you would treat the contents confidentially.

    Of course Scrivener support has to come from them - I'm assuming that the Scrivener error message is a result of the MMD6 error. The only way to resolve it is to delete the entire export directory containing the .tex file and all things that go along and start a new export from scratch.

    Email is [email blocked] -- I will treat anything as confidential and delete it when I'm finished (though it may be in email backups, etc.)

    If you need true confidentiality, you can put it in an expiring download link somewhere so the data is never in my email, but that may be overkill.

    The "missing access rights" doesn't sound like something from MMD, but if you figure out any more specifics let me know.
