When generating 64-bit code, stack slots allocated to
local variables can overlap alloca areas.
This bug may be specific to PIC code generation since the
test case I have (elf/dl-fini.c in GLIBC) is built with -fPIC.
I'm still trying to distill a small test case and, whether I
can or not, I'll attach some reproducer to this bug report.
