https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=207359 --- Comment #6 from Mark Millard <markmi@dsl-only.net> --- (In reply to Mark Millard from comment #5) The uw_update_context_1 material would have been clearler if I'd listed another line from the source code. So I do below. fs->cfa_offset is not part of regs but is later used by uw_update_context_1 for: /* Compute this frame's CFA. */ switch (fs->cfa_how) { case CFA_REG_OFFSET: cfa = _Unwind_GetPtr (&orig_context, fs->cfa_reg); cfa += fs->cfa_offset; break; . . . context->cfa = cfa; That last explains how the fs->cfa_offset is supposed to end up involved in later activity. (fs is local to each loop iteration; context's lifetime spans across iterations.) Also: I see that in at least one place I typed "12" instead of "128". Be warned. -- You are receiving this mail because: You are the assignee for the bug.
