However, we then hit PR 59472. Also, if instead of gold 1.11 (which works fine) I use GNU ld 2.24, I get warnings: /usr/bin/ld: error in /tmp/cc5iP5Yf.ltrans2.ltrans.o(.eh_frame); no .eh_frame_hdr table will be created. because of crtend.o. The path is long... At least, I tried the result, and it does help for PR 59048 and does allow removing operator delete(0).
