--- Comment #5 from niXman <i.nixman at gmail dot com> 2012-01-08 15:15:19 UTC --- I don't have other GCC versions or lto-pugins on my computer. Here is a fragment of code from gcc-4.6.2-release: fprintf (f, "%u %x %s %s\n", (unsigned int) slot, symtab->aux[j].id, lto_resolution_str[resolution], symtab->syms[j].name); This one is the same fragment from gcc-4.6.3-branch: fprintf (f, "%u %x %s %s\n", (unsigned int) slot, symtab->aux[j].id, lto_resolution_str[resolution], symtab->syms[j].name); And this one is the same fragment from gcc-trunk: fprintf (f, "%u %llx %s %s\n", (unsigned int) slot, symtab->aux[j].id, lto_resolution_str[resolution], symtab->syms[j].name);
