Yes, the problem is that the resolver function just looks
like an alias, but it actually is not. the syntax in the
assembler must look like this:
.type magic, @gnu_indirect_function
.set magic,resolver
.globl main
.type main, @function
main:
call magic
but it is all linker-magic. if you disassemle that
at runtime it looks like
main:
call implementation
I am not sure, maybe returning AVAIL_OVERWRITABLE
would be more conservative. it seems to work too.
