[GRASS5] r.slope.aspect crash - libes/gis/null_data.c

[Markus Neteler]

Hi,

today we realized a nice crash of r.slope.aspect:

r.slope.aspect elev pc=z.rsa.pcurf
percent complete: Segmentation fault (core dumped)

If you try the spearfish data:
r.slope.aspect elevation.dem pc=z.rsa.pcurf
percent complete: Segmentation fault (core dumped)

The debugger tells us that there is something strange in
libes/gis/null_data.c
Program received signal SIGSEGV, Segmentation fault.
0x8056635 in G_set_f_null_value (fcellVals=0x0, numVals=1) at null_val.c:295
/ssi0/ssi/neteler/cvsgrass/src/libes/gis/null_val.c:295:9157:beg:0x8056635
(gdb) 

Unfortunately this doesn't tell me anything? Probably the NULL
implemenation is weird in null_val.c?

To our surprise the aspect/slope calculation runs well.

It would be nice to have that fixed...

Thanks,

 Markus
