  Are you using a version of the HDF5 library that has been built with the "--enable-threadsafe" configure flag?

HI Quincey Koziol:
Thank you for your help.Today , I have resolve this problem through --enable-threadsafe. But I found , the --enable-threadsafe is incompatilbe --enable-cxx in IA 64-LINUX-SYSTEM. but it good for linux-32bit. So,I write C program for IA64-linux-SYSTEM.
