The reason for this is that are many calls to Tcl_CreateHashEntry in the
Tcl code
which don't check for NULL values. In stead of panicing, those will crash
without any clue what happened.

Actually, I thought about this, and - at the same time - do the
same for Tcl_Malloc and friends as well:
    <https://core.tcl-lang.org/tips/doc/trunk/tip/668.md>
but I don't think this will get sufficient support. Better
first improve the error-handling in the core.

Hope this helps,
