 I had hope that this commit:
 
   http://mail-index.netbsd.org/source-changes/2016/11/30/msg079412.html
 
 might have a positive effect on the situation, but it has not.
 
 There is a slight difference in behavior on the i386 machine that recently
 succeeded in building "gobject-introspection" et al (until the failure
 of "gstreamer1" provoked failure of all other problem packages).  When
 attempting to build "gobject-introspection" again, it now leaves only
 one core file, that of "g-ir-compiler" (actually
 "${WRKSRC}/.libs/g-ir-compiler").
 
 The backtrace is familiar:
 
 Core was generated by `g-ir-compiler'.
 Program terminated with signal SIGSEGV, Segmentation fault.

 There is no change in behavior on the other i386 system I updated.
 Building "gobject-introspection" leaves behind a "python2.7.core" and
 a "GLib-2.0.core" (which refers to a utility built to a temporary
 directory which is immediately removed).  The python2.7 backtrace is the
 same as has already been posted several times.
 
 I'll try on amd64 soon.  The backtraces from failures on amd64 have
 never been particularly helpful as there are never any symbols for
 the reported addresses, even with all the debugging turned on.
 
 Perhaps as described in this thread:
 
   http://mail-index.netbsd.org/tech-pkg/2016/11/29/msg017565.html
 
 the present workaround is to set "PKG_DEFAULT_OPTIONS+=-introspection"
 and hope that the problem packages honor it.
