I've checked in a patch to fix this into the upstream CVS repository. There will probably be an errate glibc with this patch. We'll add the number here once it is available. Try the code at ftp://people.redhat.com/jakub/glibc/errata/2.3.2-27.9.4/ and let us know how it works. Ulrich- I just tried the glibc that comes with Fedora, and it works great. lapham@bilbo > rpm -q glibc glibc-2.3.2-101 Mon Nov 10 (06:38 PM) [~] lapham@bilbo > LD_PROFILE=libc.so.6 ls > /dev/null lapham@bilbo > sprof /lib/tls/libc.so.6 /var/tmp/libc.so.6.profile | head -6 Flat profile: Each sample counts as 0.01 seconds. % cumulative self self total time seconds seconds calls us/call us/call name 0.00 0.00 0.00 208 0.00 readdir64@@GLIBC_2.2 An errata has been issued which should help the problem described in this bug report.
