How the GNU linker treat .eh_frame ELF section?

Question

1. Can .eh_frame or .eh_frame_hdr section of a .so shared library be overwritten by .eh_frame of another .so while loading a sequence of .so files for an executable while resolving sumbols?
2. Does .eh_frame consider relocation issues? Is it guaranteed that .eh_frame of a .so library will provide C++ try-catch correct work (exceptions doesn't cross ".so boundaries") for any binary using the code from the .so library? For example, the code in .so throws and catches all its exceptions (internally) then successfully writes error messages to a log file when called from binary A (that uses my .so library). Could linking process for some another binary B hurt the "exception mechanics" and how could that happen exactly?

Answer 1

The answer to your first question is no, and your second question appears to be exact duplicate of your earlier question.
