Dear Maintainer,
After updating my bgfx-based renderer throws assertions.
src/mesa/main/texcompress_etc.c:1130: _mesa_texstore_etc2_rgba8_eac:
Assertion `0' failed.
from glGenerateMipmap() for any of the following texture formats:
GL_ETC1_RGB8_OES
GL_COMPRESSED_RGB8_ETC2
GL_COMPRESSED_RGBA8_ETC2_EAC
GL_COMPRESSED_RGB8_PUNCHTHROUGH_ALPHA1_ETC2
Code roughly, look at (or better execute)
https://github.com/bkaradzic/bgfx/blob/7464fd16ab689a3bd736b6808a3ce9fbbeae3412/src/renderer_gl.cpp#L1461
```cpp
glGenTextures(1, &id);
glBindTexture(target, id);
glTexStorage3D(target, ...);
glCompressedTexImage3D(target, ...);
glGenerateMipmap(target); /* ASSERT TRIGGERED */
```

I guess the simplest way to replicate is to check out and run any of
the bgfx examples.
Might this be related to the change of the used assert macro in
https://gitlab.freedesktop.org/mesa/mesa/commit/bfcdb843830bba0190e00e35e3c5c18c4bdb5de1
(although that is 3 years old)
