This is not a bug but rather a design choice - it is hard to compute exact size
of preceding instruction on CISC platforms. ASan just decrements 1 because this
is enough for tools like addr2line or gdb to symbolize addresses. Replacing by
trace[i] would indeed cause invalid symbolization as you already noticed.
