#900 -p 7.0 crashes obabel

[Björn Grüning]

Hi,

the following command will crash obabel 2.3.2.
Please note if you omit the -p 7.0 option it works.

echo 'N=[N+]=NC1=C(C(=O)C)C(=O)c2c3c1cccc3ccc2' | obabel -i smi - -o smi -e -b -p 7.0

Thanks!

Hi,

turnes out PubChem has a few more compounds that are crashing obabel.

echo 'N=[N+]=NC1=NC(=O)C2(NN1)c1ccccc1c1c2cccc1' | obabel -i smi - -o can -p 7.0
echo 'N=[N+]=NC1=NN=NC2=NC=NC12' | obabel -i smi - -o can -p 7.0
echo 'N=[N+]=NC1=NS(=O)(=O)c2c1cccc2' | obabel -i smi - -o can -p 7.0

I think I can see a pattern :)

Cheers,
Bjoern

Interestingly obabel 2.3.1 has no problems with such molecules.
