It crashes in pkl_struct_type_traverse:
Thread 1 received signal SIGSEGV, Segmentation fault.
[Switching to Thread 8700.0x15b8]
pkl_struct_type_traverse (type=0x4caa6a0, path=path@entry=0x528ed20
"tag.frames[
0].") at ../../../poke.git/libpoke/pkl-ast.c:775
775 if (STREQ (field, sub))
It's happening because the field name (ename) is accessed:
ename = PKL_AST_STRUCT_TYPE_FIELD_NAME (t);
field = PKL_AST_IDENTIFIER_POINTER (ename);
But there is no field name for the padding of ID3V2_TAG:
/* Padding. */
uint<8>[hdr.get_size - (frames'offset + (frames'size))/#B];
