Bug ID: 33351
Summary: binutils/readelf.c:21026:3: runtime error: null
pointer passed as argument 1, which is declared to
never be null
Product: binutils
Version: 2.46 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: pheeck at gcc dot gnu.org
Target Milestone: ---
For many targets, if you compile binutils with undefined behaviour sanitizer
and run the testsuite...
configure --build=x86_64-linux --disable-gdb --disable-gdbserver
--disable-werror --target=alpha-linux CFLAGS="-g -O2
-fsanitize=address,undefined -Wno-error"CXXLAGS="-g -O2
-fsanitize=address,undefined -Wno-error"LDFLAGS="-ldl"
make -j64
make -j64 -k check
...the sanitizer reports UB in readelf:
grep 'runtime error' binutils/binutils.log
binutils/readelf.c:21026:3: runtime error: null pointer passed as argument 1,
which is declared to never be null
