Wow 13415 is from 13 years ago! However I have only noticed int GCC 11 and
newer, but I guess the bug could have been there much longer.
I have not looked at source code but my guess is the linker is placing the
removed code at address zero (0x000). I suspect that someone used zero(0) to
indicate the address was not valid, where address zero is really a valid
address.
As mentioned it might be possible for linker to place the removed symbols in a
different section so linker does not add to elf or make a flag/enum to indicate
the symbol has been removed such that the linker does not add symbols to the
elf file.
