Instead, passing a "negative" value actually passes a very large + value, which is probably not what the user intends and can cause + crashes on 64-bit systems. + + The Doxygen documentation has been updated and passing values larger + than UINT32_MAX for size_hint will now produce a normal HDF5 error. + + (DER - 2021/04/29, HDFFV-11241) + + + - H5Pset_fapl_log() no longer crashes when passed an invalid fapl ID + + When passed an invalid fapl ID, H5Pset_fapl_log() would usually + segfault when attempting to free an uninitialized pointer in the error + handling code. This behavior is more common in release builds or + when the memory sanitization checks were not selected as a build + option. + + The pointer is now correctly initialized and the API call now + produces a normal HDF5 error when fed an invalid fapl ID. + + (DER - 2021/04/28, HDFFV-11240) + + - Fixes a segfault when H5Pset_mdc_log_options() is called multiple times + + The call incorrectly attempts to free an internal copy of the previous + log location string, which causes a segfault. This only happens + when the call is invoked multiple times on the same property list. + On the first call to a given fapl, the log location is set to NULL so + the segfault does not occur. + + The string is now handled properly and the segfault no longer occurs. + + (DER - 2021/04/27, HDFFV-11239) + - HSYS_GOTO_ERROR now emits the results of GetLastError() on Windows HSYS_GOTO_ERROR is an internal macro that is used to produce error |
