The argument to alloca() in filelock.c:unlock_file() was about 0x20000000.
This resulted in a negative stack pointer.
The filename was a lisp string object with size 0x1fffbf6c and data "/tmp/xt"
(it was this large size which was used to compute the argument to alloca).
The pointer 0x1fffbf6c pointed to a valid lisp string with size 7 and data
"/tmp/xt".
