We managed to fix our issue.
In one of the modules of our application, we had a uint8_t* global that was initialised to point to a const string. We were then modifying that variable, meaning we were modifying constant program data. Changing the variable to an array that is initialised to the value of the const string was the fix.
Though, we're still not clear why exactly that would be causing an issue with the verifiction of a new firmware image, nor why it would panic instead of just returning an error code. If anyone has any thoughts on that it would be nice to know.

Re: Over-the-air update: Panic happens when esp_ota_end() is called
@henrysshunt,
You are right. Main cause in firmware or sizing of partition.
I tried use simple_ota_example and OTA work fine. The example sizing partitions automatically:
OTA update work properly, in example:
But when I try update firmware in my app i get error in verify step.
I think main cause in partition size, but I can't figure out where exactly(
This my app partitions size:
Update process panic at esp_image segmentation step:
Anybody know how to determine main problem?

@henrysshunt, thank you very much! I fixed issue with the same way as you said.
I reviewed and refactored each line of code and find issue with my global vars.
I have gpio_fn.h where declared prototypes of global vars:
and gpio_fn.c
after change gpio_fn.c to default init values:
OTA update works
