PR binutils/17512 * dwarf.c (display_debug_loc): Pacify the undefined behaviour sanitizer by simplifying address difference calculation. (struct Frame_Chunk): Change type of cfa_offset to dwarf_vma in order to avoid arithmetic overflows. (frame_display_row): Cast cfa_offset before printing it. (display_debug_frames): Likewise. Check for an unexpected segment size. Chnage type of 'l' local to dwarf_vma and cast it back to an int when printing. (process_cu_tu_index): Tighten check for an invalid ncols value. * readelf.c (process_corefile_note_segment): Check for inote.descdata extending beyond the end of the section. (process_v850_notes): Likewise. -- 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
