Yes, the intention is that there is the possibility to signal errors
and not just ignore them.

I would say that is impossible because c_string_to_object is just an
alias for ecl_read_from_string. From ecl/src/h/external.h

#define ecl_read_from_cstring(s)
si_string_to_object(1,make_constant_base_string(s))
#define ecl_read_from_cstring_safe(s,v)
si_string_to_object(2,make_constant_base_string(s),(v))
#define c_string_to_object ecl_read_from_cstring

Could you print the output of ecl_read_from_cstring() ? Does
si_string_to_object get called when you use c_string_to_object() ?
