Status in Hugin - Panorama Tools GUI: Fix Released

Bug description:
On a GNU/linux Ubuntu 8.10 system with hugin 7.0, enblend 3.2, I have 91Go of swap; 4Go ram (but 32bit processor)
I try to make a panorama with 70 pictures.
I reduce the output to 4000px width...
I looked at the amount of memory used by enblend and just before crashing, the use of memory rise in one time.

here is the log :
