This is a bit late, but today I was trying to display images in M5Stack Fire module, and had the same problem. After a bit of trial and error, I discovered that if the PNG file names are long, this error will trigger. And it is not easy to guess that the long file name caused it!

Tested with IDF 4.1 and I got a bunch of warnings, but build completed successfully!
Again, thanks @brus!

This is great, I was trying to build the older one with IDF version 3.3 without success. Got to give this a try, thanks!
