Can you try building the latest emacs-26 branch of the Emacs Git repository, and see if the problem happens there as well? Failing that, we'd need a backtrace to start looking into this. Perhaps download and install debug data package for your Emacs distribution, or build yourself without stripping the binary. Then repeat the recipe under GDB. Thanks.
