Subject: [Bug sanitizer/65749] sanitizer stack trace pc off by 1
Date: Thu, 16 Apr 2015 13:00:00 -0000	[thread overview]

--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
For the purpose of looking up the address in line table etc. IMNSHO the
subtraction of 1 is needed (that is what gcc unwinder does too, except for
signal frames where the pc must be on the faulting or asynchronously
interrupted insn)).  But if the addresses are printed, supposedly it should
match what the debugger does, and at least gdb prints the address after the
call instruction, not address after the call instruction - 1.
