--- Comment #86 from Nick Clifton <nickc at redhat dot com> --- Hi Alexander, > 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. I do find it useful, so please do integrate it into your reports. > 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 These should all be fixed now.
