Re: Segfault on CVS HEAD

I am seeing the following segmentation fault when doing 'gmake install'
on CVS HEAD; any idea why?

$ gmake install
/bin/sh ../config/mkinstalldirs '/usr/local/pgsql/lib/pgxs/src'
/bin/sh ../config/install-sh -c -m 644 Makefile.global '/usr/local/pgsql/lib/pgxs/src/Makefile.global'
/bin/sh ../config/install-sh -c -m 644 Makefile.port '/usr/local/pgsql/lib/pgxs/src/Makefile.port'
/bin/sh ../config/install-sh -c -m 644 ./Makefile.shlib '/usr/local/pgsql/lib/pgxs/src/Makefile.shlib'
/bin/sh ../config/install-sh -c -m 644 ./nls-global.mk '/usr/local/pgsql/lib/pgxs/src/nls-global.mk'
gmake -C port install

I rebooted my server but it didn't help. All this just started today.

Your make is buggy?

I'm not totally sure, but I think this is make reporting that install
crashed. Perhaps a corrupted install executable?

Turns out the cause was a buggy gmake that segment fauled on this:

$(if $(ZIC),$(ZIC),./zic) -d ...

It affects at least gmake 3.78.1 but is fixed in at least version 3.81.
I talked to Peter and it seemed easist to just simplify the gmake rules
and document the issue with a comment, attached.
