[9.2] seg fault for world enlargement

[sdog]

When enlarging the map from 256x256 to 1024x1024 the program reproduceably exited with segmentation fault. It is reproducible for a newly created map.

Tested with: simutrans experimental 9.2, 64 bit binary, compiled with gcc 4.4.5; pak128.gritain-ex 7.1

Test system: ubuntu 10.10, 64 bit

9.3 fixes a possible cause of a segmentation fault on map enlargement - can you let me know whether this issue recurs in 9.3?

[jamespetts]

There having been no further reports in 9.3, I shall treat this as being fixed.
