Since I do not have a Windows XP 64-bit machine, I tested your code on
Linux.
I could not reproduce the problem. Call H5Fflush() after you create the new
group to see if it solves the problem. Thanks --pc

Under some circumstances, I'm seeing an assertion errors when I create
a new dataset inside a sample HDF5 file I'd created using HDFView
Platform: Windows XP 64bit
HDF5 version: 1.8.5-patch1 (and 1.8.5), recompiled to disable SZIP
HDFView version: 2.6.1 for Windows XP
Attached is a sample application and a H5 file that result in me
getting the following assertion errors when I try to create the dataset:
Assertion failed: elem, file ..\..\..\src\H5FL.c, line 1876
Assertion failed: H5F_sfile_head_g == ((void *)0), file
..\..\..\src\H5Fsfile.c, line 65
More detail on the oddness...
In the sample H5 file, I've created some groups / datasets that I'm
using in unit tests for a wrapper around HDF5lib that I'm writing.
In the sample application, I open the file,create a group '/newGroup',
and try to create a dataset '/newGroup/newDataset' which results in
the above assertion failures
However, if I create the dataset beneath a pre-existing group in the
H5 file, either '/group1/newDataset' or just in the root
'/newDataset', I _do not_ get the assertion failures.
Also, if I create an empty H5 file via my application and then add the
'/newGroup' and '/newGroup/newDataset', I _do not_ get the assertion
failures.
So... is this some weird mismatch between the properties with which
HDFView created the groups in the test file vs. how I've got the
properties when I create '/newGroup'? What do I do to fix it?
Thanks,
Steve Christensen
