“断言失败。” 退出程序时出错 (HDF5 1.8.6)

Question

I'm using HDF5 1.8.6 on a Windows7 32-bit system from a data acquisition C#/.Net application (using the HDFDotNet wrappers).

I've noticed a runtime error(AssertionFailed) popup when I exit my application after the following behavior:

1.) I open an HDF5 file on a USB drive (or network shared drive) 2.) I start sampling data and storing it to the HDF5 file. 3.) I (rudely) remove the USB drive (or disconnect the network shared drive) 4.) Write exceptions are handled (seemingly appropriately... no crashes) 5.) I close the application.

At this point I get the error, which mentions File:......\src\H5F.c (Line 1737) and "Expression: f->file_id>0"

I'm assuming the HDF5 library is trying to clean something up and is confused that it can't find a file it was using... but it seems it should still be able to recover when it can't. Have I missed something?

Thanks!

I bet the HDF5 has a close/exit/shutdown function that you should be calling before you exit.
