Then this is an incompatibility between compiler and linker: the compiler sees a protected symbol and emits a relocation assuming it doesn't need indirect access via the GOT to do a pointer comparison, but ld.bfd says it should. Anyway, this is what I am asking to change: when a symbol is protected, the compiler optimisation should be allowed and pointer comparison still works provided ALL users use the GOT too. That includes the executable. -- You are receiving this mail because: You are on the CC list for the bug.
