- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start at LLImageGL::createGLTexture in llimagegl.cpp, especially line 1690, and trace the texture-creation path through LLViewerFetchedTexture::createTexture in llviewertexture.cpp and LLViewerTextureList::updateImagesCreateTextures in llviewertexturelist.cpp. Use the supplied macOS call stack to investigate the crash during mipmap generation; done requires identifying and resolving the crash cause, though no reproduction steps or test are named.
