Thanks Markus.
your stack trace is useful! But a bit strange:

1) In both logs the sparsersb's path seems to be 
   "C:\Program Files\GNU
Octave\Octave-6.0.90\mingw64\lib\octave\packages\sparsersb-1.0.7\x86_64-w64-mingw32-api-v55\sparsersb.oct"

   why 1.0.7 ? Are you using 1.0.8 version of sparsersb?
Version 1.0.7 is not meant to work with librsb-1.2.0.9.

2) In sparsersb_bt_pkg_test.log
 I see stack in the trace:
 sparsersb!rsb.do_util_merge_sorted_subarrays_in_place ()
 sparsersb!rsb__do_get_pixmap_RGB_from_matrix ()
 sparsersb!rsb__do_get_pixmap_RGB_from_matrix ()
 sparsersb!rsb.do_mtx_render ()

and that is very strange:rsb__do_get_pixmap_RGB_from_matrix shall not be
there.
Indeed, sparsersb.cc calls rsb_mtx_rndr, which in turn calls 
rsb__do_mtx_render.
But from there I've no idea why rsb__do_get_pixmap_RGB_from_matrix is there..
that function is being invoked by rsb_file_mtx_rndr, which sparsersb.cc does
not invoke in any way. 
Corrupt stack trace ?

3) In sparsersb_bt_render.log
 rsb.do_mtx_render seems to invoke rsb.destroy_coo_matrix_t
 This seems fine, in that rsb__do_mtx_render calls a static function which
calls rsb__destroy_coo_matrix_t.
