 some real information.

 My bad, I was calling the wrong grass72 version without debugging symbols
 in...

 > I could reproduce the problem, the segfault is caused by stack overflow
 because alloca allocates memory in the stack, while malloc and calloc
 allocate memory in the heap. I could fix the segfault by replacing
 G_alloca()/G_freea() with G_malloc()/G_free(). Please try the attached
 patch against lib/raster/.

 Thanks! r.in.gdal now runs, no more immediate crash. In some hours the
 dataset may be imported, I'll report.
