astro/wcslib fails to install

[Jan Henrik Sylvester]

My latest port upgrade (from source via portmaster) on
10.0-RELEASE/amd64 fails at astro/wcslib, which has been bumped after
the astro/cfitsio update. It fails to install with:

pkg-static:
lstat(/usr/ports/astro/wcslib/work/stage/usr/local/bin/HPXcvt): No such
file or directory

Building astro/wcslib does not fail, but there are numerous segfaults
starting with these:

make[2]: *** [libwcs-4.13.4.a(lin.o)] Segmentation fault (core dumped)
gmake[2]: *** Archive member `libwcs-4.13.4.a(lin.o)' may be bogus; not
deleted

cc -DHAVE_CONFIG_H -I. -I.. -O2 -pipe -fno-strict-aliasing -c sph.c
ar r libwcs-4.13.4.a sph.o
ar: warning: Incorrect file header signature
gmake[2]: *** [libwcs-4.13.4.a(sph.o)] Segmentation fault (core dumped)

What is happening here?

I do not have anything in make.conf that should be related (only
WITH_NEW_XORG=yes, TEX_DEFAULT=texlive, and some port specific options
of unrelated ports).

Cheers,
Jan Henrik
