After adding a large unknown value to "start", the test "start < end" depends on where "start" is originally in memory. PR 22239 * dwarf.c (read_cie): Don't compare "start" and "end" pointers after adding a possibly wild length to "start", compare the length to the difference of the pointers instead. Remove now redundant "negative" length test. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
