Segmentation Error

Hi,

I am using WRFChem version 4.4 ( chem_opt = 202 with 4-bin) and preparing chemical IC, BC using mozbc from CAMCHEM global data.

Simulations give the following error at the start of the run:

d01 2018-01-10_00:00:00 input_wrf: end, fid = 2
d01 2018-01-10_00:00:00 module_io.F: in wrf_ioclose
d01 2018-01-10_00:00:00 Input data processed for aux input 7 for domain 1
d01 2018-01-10_00:00:00 in med_latbound_in
d01 2018-01-10_00:00:00 in med_latbound_in preparing to read
d01 2018-01-10_00:00:00 module_io.F: in wrf_inquire_opened
d01 2018-01-10_00:00:00 Opening: wrfbdy_d01
d01 2018-01-10_00:00:00 module_io.F: in wrf_open_for_read

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:
#0 0x2b5a7f12b3ff in ???
#1 0x2b5a7f1777a2 in ???
#2 0x2b5a7f17b213 in ???
#3 0x2b5a7e7593a5 in data_transfer_init

#4 0x405f36b in ???
#5 0x405fc42 in ???
#6 0x1d22baf in ???
#7 0x40ee00 in ???

On the other hand, if I submit the simulation without first preparing the chemical ICBC from MOZBC, the simulation completes without any error.

I am hereby sending MOZARTMOSAIC.inp, which I am using to run mozbc.
Would you please look at the species-mapping in MOZARTMOSAIC.inp. MOZBC is running successfully with cam-chem data.
Could you please make a suggestion to me regarding this error? Any suggestions would be greatly appreciated.

Regards
Saurabh

Hello Saurabh,
Were you able to solve this issue?
I am facing a similar issue, in my case, I discovered that the same SIGSEGV error appears only when setting feedback=1, otherwise; the run goes smoothly.
