The fix then is in the last changed line of this patch, to check p->is_sym as well as p->u.syment.n_sclass. The other changes fix various overflow checks that weren't as solid as they could be. PR 25197 * coffgen.c (coff_find_nearest_line_with_names): Check that C_FILE u.syment.n_value does point at another C_FILE sym and not into some auxent that happens to look like a C_FILE. Properly check for integer overflow and avoid possible pointer wrap-around. Simplify pr17512 checks. -- You are receiving this mail because: You are on the CC list for the bug.
