[GRASS-user] Buffer error: G_realloc: unable to allocate

GRASS GRASS user

Hello!
This question may be basic, however I am struggling with that issue for a while. I am trying to make a buffer around big vector (lines mode) and it is constantly returning:

  • G_realloc: unable to allocate 178240032 bytes of memory at lib/vector/Vlib/snap.c:251

I saw a possibility to use set GRASS_VECTOR_LOWMEM=1 to reduce memory usage. I am using Windows 8, and I entered set GRASS_VECTOR_LOWMEM=1 to CMD which starts with GRASS.

However there was no difference, now I am wondering is the shell environmental variable GRASS_VECTOR_LOWMEM not set correctly or the problem is somewhere else?
Please help.
Greetings,
Peter

I don’t know much about that, but first I would try to use newly available 64-bit version of wingrass downloadable from GRASS website, that might help you.

Best,
