When the `SPV_BINARY_TO_TEXT_OPTION_PRINT` option is specified, `spvtext` will not be created (see 37d2396cab/source/disassemble.cpp (L117)), and the attempt to dereference into its members (`spvtext->str` and `spvtext->length`) results in segmentation fault.
This is fixed by first checking if `spvtext` is nulll.
