Smaller test case:
=====================================================
typedef struct {
char **visbuf;
char **allbuf;
} TScreen;
void
VTallocbuf(TScreen *screen, unsigned long savelines)
{
screen->visbuf = &screen->allbuf[savelines];
}
=====================================================
On AMD64 this gives me:
salq $3, %rsi
addq 8(%rdi), %rsi
movq %rsi, (%rdi)
ret
instead of
movq 8(%rdi), %rax
leaq (%rax,%rsi,8), %rsi
movq %rsi, (%rdi)
ret
