Stack traces for all three crashes.  They appear to all die in the same place. 
fcpat.c is likely part of the fontconfig library.  I recently built fontconfig
2.6.0 and installed it; so far as I know that's the newest stable version. 
There's also the stock Solaris fontconfig (implausibly tagged as version
6.6.2.7400,REV=0.2004.12.15, but the obvious datestamp makes the real version
number no higher than 2.2.97 and likely lower) on this host, but libcairo and
all the test binaries appear to be using the newer one.

I will note (possibly tangentially) that thread functionality -- including
pthreads -- in Solaris 10 has been folded into libc.  Using libpthread may not
be needed, and may improve things.  I've had one other package attempt to use
libpthread and fail to build, which then succeeded when I altered the build
sequence to get rid of libpthread.  I'll see if I can persuade Cairo to build
without libpthread to see if that makes a difference.
