--- Comment #7 from Gabriel Marcano <gabemarcano at yahoo dot com> --- My bug might not be the same as this bug after all. I didn't know any better, and my newlib was apparently built using -flto, which led to my symptoms. Building newlib without -flto causes linking to succeed for me. I was told that the problem is that LTO does... things to the builtin symbols, which can confuse the linker (if I understood what I was told correctly). Sorry for the noise. -- You are receiving this mail because: You are on the CC list for the bug.
