Fix incorrect memory allocation when using the VLA fallback macro in traceback.c with alloca(). The previous implementation allocated only size bytes instead of sizeof(type) * size, which could lead to out-of-bounds access.
A regression test and NEWS entry are included.
traceback.cwhenalloca()is used over VLA #145792
