Commit Message

FFI: Fix dangling CType references (again).

Reported by Sergey Kaplun.

(cherry picked from commit c64020f3c)

This patch fixes JIT recording for the vararg calls, that was not fixed
in the previous patch. The `ctr` pointer to the child cdata value may
become invalid after the ctype state table reallocation in the
`crec_call_args()`.

This patch preserves `ctr->info` in the separate variable to avoid
dereferencing an invalid pointer.

Sergey Kaplun:
* added the description and the test for the problem
