Description of problem:
If there's a CD or DVD inserted in the CD/DVD drive corresponding to /dev/cdrom, isoinfo will crash if started without arguments, but not if started as isoinfo -i /dev/cdrom. If there isn't any media in the drive, both cases will exist normally after printing the appropriate errors.
If given additional arguments (say -R, -l, -f), it will display the requested information before crashing.
In fact, it will crash on fclose, so it's quite likely just some uninitialized (or corrupted) FILE*.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Insert some media containing a filesystem in a CD or DVD drive associated with /dev/cdrom
Actual Results: It crashes
Expected Results: It shouldn't crash
So far I've only tried this on x86_64, but this might very well be architecture-independent.
Oops, filed against wrong component, sorry.
please do a:
# strace -f isoinfo
and attach the output.

strace output, as requested
I very much doubt this is going to add any info over what I've already posted,
but here it goes... FWIW, here's the crash as reported by GDB:
Program received signal SIGSEGV, Segmentation fault.
0x000000377a35c1ab in fclose@@GLIBC_2.2.5 () from /lib64/libc.so.6
The crash occurs at the instruction that first reads from the first argument,
that was (incorrectly) passed as NULL.
Bug still present in today's rawhide (mkisofs-2.01.1-10).
