Description
I compiled qtbase from dev branch with debug info and when I start sddm it crashes with glGetString call

qglxintegration.cpp:670
if (const char *renderer = (const char *) glGetString(GL_RENDERER)) {
note that glGetString points to a valid memory address.
oh, I just realized I forgot to recompile qtdeclarative. Isn't there some way for Qt to tell that it's ABI related issue and need to recompile?
So now after recompiling qtdeclarative I get this
Failed to create OpenGL context for format QSurfaceFormat(version 2.0, options QFlags(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples -1, swapBehavior 2, swapInterval 1, profile 0)
I'll submit new issue for that
