You must be confusing that with something else, perhaps weak symbols.

Local symbols never appeared in the dynamic symbol table, never did. 
Look at

    readelf -s <somebinaryordso>

and compare the .dynsym and the .symtab sections.  The latter, if 
present, contains all the symbols, while the former only contains the 
non-local symbols (the only local entries are the SECTION "symbols" but 
this is just a GNU ld thing).  The .symtab table is not loaded at 
runtime (look at the program header) so there is no way it can be looked at.

I cannot answer your question about the mysterious problems since I 
never saw them nor analyzed them.  But adding HIDDEN to a local symbol 
cannot change anything after the linker finished its work.
