--- Comment #1 from Mike Hommey <mh+gcc at glandium dot org> --- Created attachment 32812 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=32812&action=edit Corresponding assembly (compressed) This is the assembly I got with the full normal command line. But I can reproduce with the following command line: g++ -o CertVerifier.o -c CertVerifier.ii -Os -std=gnu++0x The problematic line is a cbz call, and i guess the label ends up at more than 130 bytes from the call.
