Bug 20831

Попытка достать блобы из базы paradox в отдельные файлы с помощью pxview:
$ pxview -v --blobextension=jpg -b Personel.MB Personel.db
datablock position = 2048
. . . . .
datablock position = 1902592
*** stack smashing detected ***: pxview terminated
Аварийный останов

При экспорте без указания расширения или импорте в mysql то же самое. Без блобов в mysql импортируется, лишь ругается после каждой записи:
Couldn't get blob data for 1 (2, 3...)

Вывод с valgrind:

$valgrind -v pxview Personel.db -b Personel.MB
datablock position = 1886208
datablock position = 2738176
datablock position = 1902592

К сожалению, файл приложить не могу. Но он, вероятно, цел, с ним успешно работает виндовая СУБД.
