Thanks, it is clear where the error lies:

Configuring with --enable-fake-main should not be necessary on
GNU/kFreeBSD, because libkvm is supposed to do its job, obtaining the
process arguments as expected.  --enable-fake-main is a last resort,
for platforms where this information cannot be gathered.

For now, I am hesitating to reassign, because that may be a bug in
gnustep-base in its [HAVE_KVM_ENV] code.

Can you compile (just `make', you need libgnustep-base-dev) and run
the attached test program this way:

while true; do for d in `expr $((d + 1))`;  do ./obj/test `seq $d`; done; done

Obviously, NSProcessInfo + libkvm works in the usual scenario (few
arguments), otherwise many GNUstep packages would FTBFS on
GNU/kFreeBSD (the build process invokes programs like pl2link with
arguments).
