could you run a 'bt' at that gdb prompt? It may give a little additional context info.

Hi, Thanks for the reply. Running bt at the prompt shows:

It looks just like memory corruption. It's unlikely that Haiku is the cause here, it's probably an application bug.

[kallisti5]

pushing to beta1 as Axel confirms that Haiku is not likely the cause and the app is 3rd party binary without sources

It's not a segmentation fault, and running under the guarded heap produces the exact same result. Instead, it's a divide error; specifically on ​this line.

If you add the following printf to the function just before the modulo:

printf("hash table size: %" B_PRId32 ", %" B_PRId32 "\n",
    fHeader->hash_table_size, fHeader->format);

you will always get the following output just before the crash:

hash table size: 0, -42

Printing other fields show they are often uninitialized memory, but hash_table_size is always 0 and format is always -42 no matter what.
