 With some instrumentation:
 
 makemessage: realloc 0x4c08df0 -> 0x4c1a170
 thread_fix_new_links: head = 0x4c08df0,  message = 0x4c1a170, omsgCount = 0, msgCount = 1
 mail: thread.c:515: thread_fix_new_links: Assertion `message_array.t_head == message' failed.
 Aborted (core dumped)
 
 So the crash is indeed caused by a missing update after realloc in
 makemessage moves the memory.
