--- Comment #82 from Alexander Cherepanov <cherepan at mccme dot ru> --- Created attachment 8108 --> https://sourceware.org/bugzilla/attachment.cgi?id=8108&action=edit Problems with `readelf -agteAruhlsSdIncVWw --dyn-syms -D` (32-bit) -- ubsan This is an experimental report. Attached samples expose undefined behavior. The errors are collected with binutils built with gcc-4.9 -fsanitize=undefined (exact configure is in configure-ubsan.txt). It it's useful I'll integrate it into the usual reports. It it's not useful feel free to ignore it. ---------------------------------------------------------------------- ubsan Files: 12 Errors: 1 ../../../source/binutils/dwarf.c:2771:3: runtime error: variable length array bound evaluates to non-positive value ... 1 ../../../source/binutils/dwarf.c:279:45: runtime error: shift exponent ... is too large for 64-bit type 'long long unsigned int' 1 ../../../source/binutils/dwarf.c:3781:4: runtime error: variable length array bound evaluates to non-positive value ... 1 ../../../source/binutils/dwarf.c:451:7: runtime error: variable length array bound evaluates to non-positive value ... 1 ../../../source/binutils/dwarf.c:5884:6: runtime error: variable length array bound evaluates to non-positive value ... 1 ../../../source/binutils/dwarf.c:5892:4: runtime error: variable length array bound evaluates to non-positive value ... 1 ../../../source/binutils/dwarf.c:6431:3: runtime error: signed integer overflow: ... * ... cannot be represented in type 'int' 1 ../../../source/binutils/dwarf.c:6437:29: runtime error: signed integer overflow: ... * ... cannot be represented in type 'int' 1 ../../../source/binutils/dwarf.c:6447:3: runtime error: signed integer overflow: ... * ... cannot be represented in type 'int' 1 ../../../source/binutils/dwarf.c:6453:29: runtime error: signed integer overflow: ... * ... cannot be represented in type 'int' 1 ../../../source/binutils/dwarf.c:6460:40: runtime error: signed integer overflow: ... * ... cannot be represented in type 'int' 1 ../../../source/binutils/dwarf.c:6469:40: runtime error: signed integer overflow: ... * ... cannot be represented in type 'int' 1 ../../../source/binutils/readelf.c:15068:46: runtime error: signed integer overflow: ... - ... cannot be represented in type 'int' 1 ../../../source/binutils/readelf.c:1615:7: runtime error: negation of ... cannot be represented in type 'long long int'; cast to an unsigned type to negate this value to itself 1 ../../../source/binutils/readelf.c:1627:6: runtime error: negation of ... cannot be represented in type 'long long int'; cast to an unsigned type to negate this value to itself -- 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
