The issue is probably lying here: https://github.com/cnjinhao/nana/blob/ffa170b5f560dbf899030bdeb0e539aa95b03649/build/cmake/enable_png.cmake#L6-L20 - `# todo: decide - PUBLIC vs PRIVATE` - the choice is easy: if you use PNG library only in private code, make...

Just checked and pulled newest code, it works on `742cde9779d74e4bdd9bff293b0004129d50f700` but was crashing on `ffa170b5f560dbf899030bdeb0e539aa95b03649`. Now, after full rebuild of nana I can't reproduce it.

Apparently it was an invalid build bug or mixed code from multiple builds. I checked dlls that are loaded by the binary and everything is ok (previously I had a...

Ok, I have found that the crashing is related to build flags, notably link-time optimization. When I add `set(CMAKE_INTERPROCEDURAL_OPTIMIZATION TRUE)` (which means `-flto -fno-fat-lto-objects` for GCC), the program crashes upon...

I suspect that there is some bug in font or UTF convertion code that is only visible when applied some optimizations. Will debug and report if I find anything.
