[Qgis-developer] Problem with large attribute tables

[Marco Hugentobler]

Hi Otto,

The problem is that you run out of virtual memory (RAM and swap partition are 
full) and so the bad_alloc exception is thrown.
In the short run we should add a try/catch block and in the long run not read 
all the rows into memory. Please write a bug report about it.

Regards,
Marco
