   use ASAN to build code and reproduce the case,stack as above;
   In thread T653,Page try to deconstruct slice's data,but failed,the address is 0x60e0005e6ba8;
   the 0x60e0005e6ba8 is allocate in  a new BitshuffleBuilder;
   The address transfer chain as below:
   BitshuffleBuilder.fastring.data() => BitshuffleBuilder.finish =>  ColumnWriter.pages.data.data => delete ColumnWriter.pages.data.data
   the key point is:if faststring didn't GrowArray,the fastring.data() is not a array when using new to allocate;
   So I use faststring.release to instead of fastring.data() in all PageBuilder, then the core dump is fixed
