Hi again, how did you install your glibc? Recently I have privately received a PR *identical* to yours, which was due to two different versions of glibc, a 2.1.x and a 2.2.x, installed unded /usr (2.1.x) and /usr/local (2.2.x). Thanks, Paolo. http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=5553
