I'm not sure this is the case of this problems...
I think missing __register_frame_info problem was caused by egcs.
When egcs compiles binaries, it will produces __register_frame_info
and so on, so it should be linked with libgcc.a of egcs, which is
in case you build shared library.
However, libc6 (and maybe other shared libraries) may not be linked
with libgcc.a of egcs, so missing __register_frame_info happens.
If this is the case of the problem here, the solution, I think, is:
- compile with gcc 126.96.36.199, not with egcs
- linked with libgcc.a of egcs, that is, add -lgcc when linking *.so.
