[GRASS-user] WxGUI Vector Digitizer crashes

Hi,
working with grass 6.4 release branch (r51019) on a debian linux system,
vector digitizer sometimes crashes after a long time of use, running out
of memory : 100% of 6GB RAM is progressively used, never decreases while
GUI is not restarted. It occurs especially when a raster background has
to be displayed. No idea what to do to help diagnose the problem (?),
looks like there is something wrong with memory deallocation.
Is it worth opening a ticket for it or can the problem be due to my
system ?

Thanks,
Vincent.

working with larger vector maps? Probably DEBUG and WX_DEBUG messages
could help (last few lines before crash).

g.gisenv set=DEBUG=5
g.gisenv set=WX_DEBUG=5

Needs some more investigation, ... Martin

Thank you Martin,
wxgui does not actually crash; but it becomes very slow when ram gets
saturated. Vector map I edit is not that big :

Number of points: 0 Number of areas: 1200
Number of lines: 0 Number of islands: 268
Number of boundaries: 2593 Number of faces: 0
Number of centroids: 1192 Number of kernels: 0

neither background raster :

Rows: 1906
Columns: 2247
Total Cells: 4282782
