Table.read segfaults on CSV file with missing comma in header
See original GitHub issueFor this CSV file with a missing trailing comma in the header line
aaa,bbb
1,2,
3,4,
I’m getting a segfault from Table.read:
$ python -c 'from astropy.table import Table; Table.read("test.csv")'
Segmentation fault: 11
This is with Python 3.5.2, Numpy 1.11.1 and Astropy 1.2 from Macports on latest Mac OS X.
Here’s the crash report: https://gist.github.com/cdeil/164d4d5ee14b49598e0454873ff0ea04#file-gistfile1-txt-L34

@mdmueller, @taldcroft or anyone familiar with the astropy.io.ascii cparser: can you reproduce or do you need more info?

Having a quick look to it, now that I know a bit the tokenizer code, it should be easy to fix. I will open a PR later.
#5219 is a duplicate of this and I’ve closed it.
