Eli, you were correct. Msys2 developers enabled ASLR by default in
binutils 2.36 (
https://www.msys2.org/news/#2021-01-31-aslr-enabled-by-default ).
I was able to avoid the segfault by adding those switches to
LD_SWITCH_SYSTEM_TEMACS in src/Makefile. Adding them as generic LDFLAGS
works too.
Maybe it's worth documenting this problem in nt/INSTALL.W64, but since
unexec is kinda deprecated I'm not entirely sure...
This leaves only the main branch unexec problem. I was able to reproduce
it with MinGW. I'll report later if my debugging results in any other
useful info.
