The kernel version is not very interesting for a userspace program like
GNU make.  But, it would be interesting if you could provide the
version of libc you are using; on my system I can use:

  ~$ /lib/x86_64-linux-gnu/libc.so.6 --version | head -n1

You can find the library by running "ldd make | grep libc'

It's also interesting you're running with "env -i" that seems like it
might be related.  Do you get the crash if you run without that?

A quick check on my system was not able to show any issues using the
same setup as you, even building make with ASAN.  I will review the
code especially around memory handling in the child structures to see
if I can find an error by inspection.
