Description David Nečas 2006-11-14 18:42:28 EST

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:
It complains one has to give it a file to dump.


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'.
Program terminated with signal 11, Segmentation fault.

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

Comment 1 Ed Hill 2006-11-14 22:12:05 EST

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 11:05:45 EST

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.
