doctest devel/sage/sage/graphs/graph_list.py fails on Solaris 10 (SPARC)

[sagetrac-drkirkby]

== Details of the computer ==

• Sun Blade 1000
• 2 x 900 MHz UltraSPARC III+ CPUs
• 2 GB RAM
• Solaris 10 03/2005 (first release of Solaris 10)
• gcc 4.4.3 (uses Sun linker and assembler)

== Sage version 4.3.3 (with several patches) ==
I'm using a patched version of Sage 4.3.3, built as a 32-bit binary. The patches include:

• GCC reports incorrect flags compiling descent_two_isogeny.c on Solaris 10 #7867 Python patch, to allow Sage library to build.
• Add iconv needed for Solaris, and possibly Cygwin too #8191 Addition of iconv, which is needed for R
• Update R's spkg-install to work on Solaris #8285 Update R's spkg-install to work on Solaris
• cddlib-094f.p4 has a useless check for mpir which breaks on Solaris #8363 Remove a useless check for mpir in cddlib
• Numerical noise in devel/sage/sage/symbolic/pynac.pyx #8375 Numerical noise in devel/sage/sage/symbolic/pynac.pyx
• Numerical noise in devel/sage/sage/symbolic/constants_c.pyx #8374 Numerical noise in devel/sage/sage/symbolic/constants_c.pyx
• Error building pyprocessing on Solaris SPARC after changes to python #8371 Patch to allow pyprocessing to build - it failed after python was patched as GCC reports incorrect flags compiling descent_two_isogeny.c on Solaris 10 #7867. (Note remove the pyprocessing spkg from sage, then sort out any fallout that results #6503 aims to remove pyprocessing completely).

== The problem ==
There are 8 test failures on this rather old SPARC. Increasing SAGE_TIMEOUT allowed 3 to pass. The longest is "devel/sage/sage/rings/polynomial/symmetric_ideal.py" which takes 459.4 s.

However, 5 failures remain outstanding.

    sage -t  "devel/sage/sage/graphs/graph_list.py" # Segfault
    sage -t  "devel/sage/sage/graphs/generic_graph.py" # Segfault
    sage -t  "devel/sage/sage/graphs/graph.py" # Segfault
    sage -t  "devel/sage/sage/graphs/graph_database.py" # Segfault
    sage -t  "devel/sage/sage/databases/database.py" # Segfault
