under special conditions the pythondriver ends in a segmentation fault.[...]
Please look at 7. and 8. These querys result in a Segmentation fault, please note that 9. and 10. do not result in a segfault, but 8. does. (9 and 10 select the same rows a 8. does, but only 8. crashes)
Would it be possible to create a short python script that demonstrates this bug. The important details are probably the row size of the table, the individual sizes of the LONGs and the PACKET_SIZE kernel parameter.
Does this error occurs when the SELECT is executed, when the row is fetched or when the content of the LONG is read?
A kernel trace (http://sapdb.2scale.net/moin.cgi/VTrace) would be also helpful tyo make sure that the demo script behaves exactly the same.
I guess that the Python driver doesn't handle some border condition. Case 8. and 9. probably return the rows in a different order, so the layout inside the communication packet wil look different.
