If I compile (configure) grass6.4 svn with this:
CFLAGS="-O2 -march=pentium-m -Wall" LDFLAGS="-s" ./configure ...

I get a "segmentation fault" message:
v.mkgrid map=pp grid=12,12 position=region --o
Segmentation fault

No error if I compile (configure) with this:
CFLAGS="-ggdb -Wall -Werror-implicit-function-declaration" ./configure
....

Comment (by neteler):

What is the gcc version (gcc -v)? There seems to be a problem with the
optimization.

Paolo, can You, please, compile v.mkgrid with also "-g" flag and then run
it in gdb.
Also provide region information.

If I compile with this:
CFLAGS="-O2 -march=pentium-m -Wall -g" ./configure ...

gdb `which v.mkgrid`

...
(gdb) run myvectgrid position=region grid=12,12 box=1,1 --o

Starting program: /usr/local/grass-6.4.svn/bin/v.mkgrid myvectgrid

Comment (by msieczka):

Paolo,

What GDAL version do you use? If you use GDAL 1.5.2 + SVN r14997 or
greater is the problem gone? I suggest to close the ticket then.
