If you compile LibreDWG with --enable trace and run:
export LIBREDWG_TRACE=9; ./test fileR14.dwg it crashes.

In file common_entity_handle_data.spec #line 17,18:

if (!FIELD_VALUE(isbylayerlt))
FIELD_HANDLE(ltype, 5);

is expanded as (pseudocode):
if ( !isbylayerlt)
HANDLE_ltype();
printf(stderr, "linetype %s", HANDLE_ltype);
#crashes because allways print HANDLE_ltype

If change the code to:
if (!FIELD_VALUE(isbylayerlt))
{
FIELD_HANDLE(ltype, 5);
}

is expanded as (pseudocode):
if ( !isbylayerlt)
{
HANDLE_ltype();
printf(stderr, "linetype %s", HANDLE_ltype);
{
#only print if linetype is decoded
