--- Comment #11 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> --- Created attachment 47878 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47878&action=edit Source and compiler output for string.c with stack-protector disabled (In reply to Oleg Endo from comment #10) > It's difficult to see what's going on there.

I have stripped "-fstack-protector" and "-fstack-protector-strong" from the CFLAGS, still crashes. Attaching the corresponding tarball of the string.* files. I can try removing more flags from CFLAGS and see if that helps.
