WARNING: tmax smaller than tmin at doy and Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Hi, I am setting up the mHM model for my basin data. After ensuring the environment was configured correctly, I encountered an error while running the model from version 5.12, which I understand may be due to the calculation of PET using tmax and tmin with the Hargreaves approach. I found that this issue was already discussed and fixed in version 5.13 (https://git.ufz.de/mhm/mhm/-/issues/242).

Therefore, I upgraded from version 5.12 to 5.13 and tried running the model using ./mhm --quiet. However, I am now facing new errors.
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Segmentation fault (core dumped)

I have carefully checked the meteorological grids, including data types, etc, multiple times, but I still cannot identify the cause. What could be the possible reason for this?

It's great that you are trying to set up mHM. It's hard to diagnose this issue from far away. Let's have a look at this newt week.
