Bug ID: 33625
Summary: SEGV in bfd/elf64-hppa.c:2372, target hppa64-linux
Product: binutils
Version: 2.46 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: pheeck at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-pc-linux-gnu
Target: hppa64-linux
If you configure binutils like this
./configure --build=x86_64-linux --disable-gdb --disable-gdbserver
--disable-werror --target=hppa64-linux
and run the testsuite.
make -j16 && make -j16 check -k
In ld/ld.log, you find
./ld-new -z nomemory-seal -L/home/fkastl/foo/binutils-gdb/ld/testsuite/ld-elf
-pie --no-dynamic-linker -o tmpdir/dump tmpdir/pr22269.o
Executing on host: sh -c {./ld-new -z nomemory-seal
-L/home/fkastl/foo/binutils-gdb/ld/testsuite/ld-elf -pie --no-dynamic-linker
-o tmpdir/dump tmpdir/pr22269.o 2>&1} /dev/null dump.tmp (timeout = 300)
spawn [open ...]
failed with: <>, no expected output
FAIL: PR ld/22269
If you run
./ld-new -z nomemory-seal -L/home/fkastl/foo/binutils-gdb/ld/testsuite/ld-elf
-pie --no-dynamic-linker -o tmpdir/dump tmpdir/pr22269.o
it segfaults.
I originally discovered this with Address Sanitizer. It provides a stack
trace:
elf64-hppa.c:2372:50: runtime error: member access within null pointer of type
'struct bfd_section'
