Thanks for analyzing. I have seen the same issue on my side. But I would like to suggest to fix it in libgo/sysinfo.c instead, seems more correct. Can you send a patch to gcc-dev and Cc me to see what the gcc developers say? best regards Waldemar _______________________________________________ devel mailing list devel@uclibc-ng.org https://mailman.uclibc-ng.org/cgi-bin/mailman/listinfo/devel
