    SubjectSIGSEGV on fclose.
    On linux I get a SIGSEGV, Segmentation fault if I close a nonopen file.

    On unix platforms, this is either simply ignored or an appropiate
    errormessage is returned, and according to the linux manualpage fclose
    on linux should return EBADF.

    I have testet the following example on AIX 4.3, Solaris 7, FreeBSD 4.0,
    TRU64, HPUX 10.20, SCO ODT5, linux kernel 2.2.15 and linux kernel
    2.2.13.

    in case you wonder: the problem arises from a program that closes a
    file twice because it does not know that the file is allready closed.

    Regards,
    Bjarne

    #include <stdio.h>

    FILE *new;

    main () {

    fclose (new); /* <---- SIGSEGV on linux only */
    }
