            Bug ID: 119029
           Summary: [15 regression] abi_check FAILs on Solaris with gld
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
  Target Milestone: ---
            Target: *-*-solaris2.11

I've only now noticed that the libstdc++ abi_check test FAILs on Solaris (both
SPARC and x86) when gcc is configured to use gas and gld:

FAIL: libstdc++-abi/abi_check

1 incompatible symbols
0
_ZSt21ios_base_library_initv
std::ios_base_library_init()
version status: incompatible
GLIBCXX_3.4.32
type: function
status: added

That already happened between 20240405
(592536eb3c0a97a55b1019ff0216ef77e6ca847e) and 20240412
(a76f236e084cbd02e4e3711cdfc3191dc7eeb460).

Unlike the gas/ld (and as/ld) builds, this configuration has
_GLIBCXX_SYMVER_GNU
defined instead of _GLIBCXX_SYMVER_SUN.
