("isdata" looks strange?). You would need to look at the structures referenced by "S" and "files"; the pointers alone don't suffice. > It crashes in i.smap/shapiro/write_img.c line 23: > files->outbuf[col] = (CELL) S->ClassSig[class].classnum; > #2 0x000000000040216b in main (argc=5, argv=0x7fff87ab2cc8) at main.c:48 > S = {nbands = 17, nclasses = 0, title = 0x74c320 " Labels", > ClassSig = 0x0} It looks like S->ClassSig is NULL, hence the segfault. This suggests that the sigset file doesn't have a "class:" tag or is broken. main() calls read_signatures(), which calls I_ReadSigSet(). This calls I_InitSigSet(), which initialises the ClassSig field to NULL, then processes the tags. If it finds a "class:" tag, it calls get_class() which calls I_NewClassSig(), which sets the ClassSig field. -- Glynn Clements <gl...@gclements.plus.com> _______________________________________________ grass-dev mailing list grass-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-dev
