bug#18270: Crash in latest emacs-24 branch on ubuntu 14.04

User-agent: Mozilla/5.0 (X11; Linux x86_64; rv:31.0) Gecko/20100101 Thunderbird/31.0

The backtrace looks like nonsense, unfortunately, e.g., it shows two arguments to adjust_decode_mode_spec_buffer, a function that has just one argument, and it shows xrealloc being called with size=18446744073709551597, even though the code passed FRAME_MESSAGE_BUF_SIZE (f) + 1 as the size, and I don't see any way to get 18446744073709551597 even if overflow is taken into account.

Can you reproduce the problem?

Can you compile with '-g3 -O0' and reproduce the problem?
