elf: Check for corrupt symbol version info
The BFD linker with PR ld/23499 may generate shared libraries with
corrupt symbol version info which leads to linker error when the
corrupt shared library is used:
/usr/bin/ld: bin/libKF5Service.so.5.49.0: _edata: invalid version 21 (max 0)
/usr/bin/ld: bin/libKF5Service.so.5.49.0: error adding symbols: bad value
Add check for corrupt symbol version info to objdump:
00000000000af005 g D .data 0000000000000000 <corrupt> _edata
and readelf:
728: 00000000000af005 0 NOTYPE GLOBAL DEFAULT 25 _edata@<corrupt> (5)
bfd/
PR ld/23499
* elf.c (_bfd_elf_get_symbol_version_string): Return
_("<corrupt>") for corrupt symbol version info.
binutils/
PR ld/23499
* readelf.c (get_symbol_version_string): Return _("<corrupt>")
for corrupt symbol version info.
