-fvisibility=hidden is indeed already used in many modules; this had temporarily
escaped me. A proper fix for this issue needs to address three things:
1 Enable -fvisibility=hidden in modules that cause warnings (=errors) with GCC
4.2 (at least configmgr and sccomp), to remove the warnings. These modules
typically use linker map files to determine their exports; the relevant symbols
need to be decorated with SAL_DLLPUBLIC_EXPORT/IMPORT in the source code, so
that they are still exported despite -fvisibility=hidden (and the linker map
file should still be used, so that the symbols get the correct versioning; at
least an experiment I just conducted showed that SAL_DLLPUBLIC_EXPORT +
-fvisibility=hidden + linker map file preserved the symbol versioning specified
in the linker map file).
2 Broken C++ exception classes like rtl::MalformedUriException need to be
fixed, so that they work reliably in all modules using -fvisibility=hidden (old
and new). This is moved out to issue 95428.
3 It has to be evaluated that any external C++ exception classes (from std::
and maybe elsewhere) are similarly safe. (I *think* I evaluated that before, but
cannot right now find any notes.)
