    Hi,

    I am experiencing some strange behaviour in my code recently, and the
    code has not
    been modified. Insofar as I can see, the only change to the system has
    been an upgrade
    to the kernel, as I am currently running 2.4.0-test9. The version of
    glibc is 2.1.3 and was
    installed via an rpm from rpmfind.net. The symptoms of the problem are
    hangs in
    getchar, getc, fgets etc. and segvs in usleep. gdb backtraces show that
    these problems
    are occuring within glibc (_IO_read -> poll and nanosleep respectively
    -- although I am
    only approximating the names from memory).

    Is this a known problem? Is this a problem with my setup? Should I be
    using a different
    glibc? Should I build glibc every time I change the kernel, or every now
    and then? I have
    asked most of these questions before, but now as applications which were
    running do
    so no longer I feel the need to ask again ;-)

    Thanks,

    Richard
