And sometimes I see the crash on a different line in the same function:

  248│ void
  249│ _mesa_reference_shader_program_(struct gl_context *ctx,
  250│                                 struct gl_shader_program **ptr,
  251│                                 struct gl_shader_program *shProg)
  252│ {
  253│    assert(ptr);
  254│    if (*ptr == shProg) {
  255│       /* no-op */
  256│       return;
  257│    }
  258│    if (*ptr) {
  259│       /* Unreference the old shader program */
  260│       GLboolean deleteFlag = GL_FALSE;
  261│       struct gl_shader_program *old = *ptr;
  262│
**263├>      assert(old->RefCount > 0);
