I have compiled WRF4.7.1 DA 3DVAR with CRTM. WRFDA installation was successful, and expected executables were created. I am trying to assimilate gfs.t00z.prepbufr.nr data. However, I’m facing issues while running da_wrfvar.exe. Sometimes WRF-Var completed successfully, and sometimes it failed. While checking rsl.error.0000 I’m getting a segmentation fault error and in rsl.out.0000 it is showing
There are 1 HDF5 objects open!

I cannot figure out what the issue is. I have experimented with reinstalling everything, but still the same error. The same data assimilation experiment with BUFR data worked fine when tested on WRFDA 3.8 installed using Intel Composer XE 2013. WRFDA worked fine for 4.7.1 when I tried to assimilate sounding data in ASCII format using OBSPROC and 3DVAR. Is this problem related to oneAPI compiler? Any suggestion will be of great help.
