Description of problem:
ncdump segfaults when run without any arguments.


Version-Release number of selected component (if applicable):
netcdf-3.6.1-4.fc6


How reproducible:
Always.


Steps to Reproduce:
1. ncdump

  
Actual results:
Segmentation fault (core dumped)


Expected results:

Additional info:
Backtrace:
Running: gdb /usr/bin/ncdump ./core.17342
Using host libthread_db library "/lib64/libthread_db.so.1".
Core was generated by `ncdump'.

It probably tries to parse NULL or something like that...

Hi David,

I'm able to reproduce this bug on i386 as well.  And it doesn't 
appear to be specific to the Fedora netcdf package.  So I've 
reported it to the upstream folks:

http://www.unidata.ucar.edu/software/netcdf/
http://www.unidata.ucar.edu/support/help/MailArchives/netcdfgroup-list/maillist.html

and hopefully it'll be fixed in a future release.

Comment 2 Ed Hill 2006-11-15 16:05:45 UTC

Upstream reports that this issue is fixed in 3.6.2beta.  And I'll update the 
Fedora package soon after the upstream 3.6.2 final release.
