Aargh.  I spoke too soon.  For my previous mail, I fat-fingered my command 
line, and ended up compiling with:
$ gcc -o foo foo.c -lsigsegv -Dsigsegv
instead of the intended
$ gcc -o foo foo.c -lsigsegv -Dlibsigsegv

Of course, given the code, that meant I wasn't using libsigsegv like I thought 
I was.  So, with my typo corrected, I'm (unfortunately) still seeing libsigsegv 
interference:

$ ./foo
fclose -1, errno 9
Aborted (core dumped)

But this front may still have hope.
