--- Comment #1 from Dimitry Andric <[email protected]> ---
I tried reproducing this crash on a freshly installed 11.3-RELEASE amd64
machine, but it works just fine for me:

It does not even use a lot of memory, roughly 143 MiB.  So is there anything
special about your build system?  Does it have very little RAM, or run a large
amount of parallel jobs?
