v.mkgrid - segmentation fault

[paoloC]

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 ....

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.

Replying to marisn:

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

gdb which v.mkgrid

This is a known issue with GDAL:

[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.

[paoloC]

Sorry. Of course, ticket must be close. Many thanks.
