Hm, on x86_64 pg inserts: fprintf (file, "\tleaq\t%sP%d@(%%rip),%%r11\n", LPREFIX, labelno); fprintf (file, "[EMAIL PROTECTED](%%rip)\n", MCOUNT_NAME); So, it loads %r11 and calls mcount. The only thing that can go wrong is, that some value in %r11 gets rewritten. Could you look what happens with %r11 around the point of failure? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32450
