iconv dumps core running make check on Solaris (SPARC)

[drkirkby]

The iconv package, which will be added to Sage (#8191), dumps core on Solaris 10 SPARC, though all tests pass on Linux, OpenSolaris and OS X.

Here are the results from a Sun Blade 2000, with Solaris 10 03/2005. The bug has been reported to bug-gnu-libiconv at gnu.org

Running gdb on the core file I see:

(gdb) target core ./core
Core was generated by `printf B<0x%010000x><0x%010000x>se B<0x%010000x><0x%010000x>bchen\n 0xC3 0xB6 0'.

I'm now told by the iconv developers this is a Solaris bug:

You see "Segmentation Fault - core dumped" messages, but the test suite
continued to run and passed. ("make" did not report a failing target.)

The 'check-subst' file contains a comment about the origin of these messages:
  # This printf command crashes on Solaris 10.
  # See <http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6550204>.

So, it does not indicate a bug in GNU libiconv, only in a Solaris program that
is used by the testsuite. Harmless.

I expect with some patches, this could be solved, as it was fixed several years ago, but I'm testing this on an early release of Solaris.
