As I don't use the renderd, but only mod_tile you need to help me fix it. Please compile the tool with debug information enabled (option -g) and do the same command in gdb - First call "gdb render_list" and then "run ...args...".

Result should be a much more specific error position which helps to find the issue. Please supply that information.

I might have the same issue.

Here is the result I have runing with gdb :

Thanks. Please enter "bt" at the end and give me the output. The carash happens in a scanf() system call.

Please try r28628. It hopefully solves that issue. One of the many printf calls I changed actually was a scanf call :-)
