[GRASSLIST:2833] core dumps after i.rectify

[grass at gevaerts.be]

Hi,

I am using Grass 5.0pre2 on a linux system (debian unstable , kernel
2.4.16, gcc 2.95.4)

After importing an image with r.in.tiff and rectifying it with i.rectify
(after doing all intermediate steps), every tool I tried coredumps on the
resulting raster (d.rast,r.support,r.compress,nviz,...)
The backtrace is :

(gdb) bt
#0  0x400c3c3b in free () from /lib/libc.so.6
#1  0x400c3ac3 in free () from /lib/libc.so.6

    mapset=0x809aa28 "PERMANENT", colors=0xbffff8f8, overlay=0, invert=0, 
    data_type=0) at display.c:134
#5  0x0804a34d in display (name=0x809a8d8 "meren",

#7  0x4006e65f in __libc_start_main () from /lib/libc.so.6

(for d.rast, the others are identical from G_close_cell up, except that
nviz crashes on line 75 in closecell.c)

line 75 is :  free (FCB.row_ptr);
line 76 is :  free (FCB.col_map);
 
FCB seems to be :

Is this a known problem, or am I doing something wrong ?
Please ask if you need more info
