Oh, you're right, sorry. Just re-downloaded the object files from the bug
tracker here and ran the linker again.

We also did some more tests and it turns out that binutils work fine when
compiled with gcc-4.6, so it seems to be an issue with gcc-4.9.

Here is the run with the proper object files nevertheless:

address@hidden:~/adrian-ldtest$ ld -v
GNU ld (GNU Binutils for Debian) 2.24.90.20141104
address@hidden:~/adrian-ldtest$ ld -shared --eh-frame-hdr -o test.so test1.o
test2.o --print-map
ld: .eh_frame_hdr table[0] FDE at 00000500 overlaps table[1] FDE at 00000528.
