I asked a glibc maintainer whether it would be possible to work around the issue. I know from debugging that there is at least one varable in the code that's placed in .data.rel.ro and assigned to. So, the const qualifier can't be used for it. As things stand, glibc doesn't build with GCC 4.6 and later. One fix might be to provide an option to set the SECTION_OVERRIDE flag. Another might be to issue a warning rather than an error on section conflicts. Dave
