Bug ID: 28622
Summary: Common symbol version information wrong in
ld.bfd-linked library
Product: binutils
Version: 2.35.2
Status: NEW
Severity: normal
Priority: P2
Component: ld
Assignee: unassigned at sourceware dot org
Reporter: tbaeder at redhat dot com
Target Milestone: ---
Using this reproducer script:
#!/bin/sh
echo '.globl foo' > foo.s
echo '.comm foo,1,1' >> foo.s
# foo version in lib1.so is Base
gcc -shared -fPIC -o lib1.so foo.s
objdump -T lib1.so | grep foo
# foo's version in lib2.so is now ""
gcc -shared -fPIC -o lib2.so -L. -l1 foo.s
objdump -T lib2.so | grep foo
foo's version in lib1.so ends up being "Base". This reproducible with ld.bfd,
lld and gold.
However, foo's version in lib2.so ends up being "" (no version information
given). That *only* reproduces with ld.bfd and not with lld or gold.
Using the latter two, foo's version is Base in lib2.so as well.
