texturec fails to compress non-square textures to ETC2A and ETC2A1

[ANTONBORODA]

As per title, texturec fails to compress any PNG texture that is not square (even if it has power of 2 size of the sides, but not square) with this output:

Error:
Failed to create output: ''

Tried on both macOS and windows. Same results on both.

Provide texture, and command line you're using.

Here you go:
etc2test.png.zip (zipping it to make sure it's not going through any transformation on github side).
Command: ./texturec -f etc2test.png -o test.dds -t ETC2A (or -ETC2A1, doesn't matter).
