I suspect that your 'diff' program is buggy, and sometimes dumps core. You might try substituting GNU diff.

The shell reported a core dump, but the test still succeeded. Can you do this to find out more? cd tests ./testsuite -v -d 225 > 12: autoupdating AC_PREREQ FAILED (tools.at:570) This I just sent you mail about already. > 150: AC_CHECK_SIZEOF struct FAILED (semantics.at:304) > ... > 222: AC_STRUCT_TIMEZONE FAILED (actypes.at:15) These seem to be failing for similar reasons: looking at the test logs, it appears that 'diff' dumped core. Can you reproduce the problem, as follows? cd tests/testsuite.dir/150 ls -l state-ls.before state-ls.after file state-ls.before state-ls.after diff -u state-ls.before state-ls.after diff state-ls.before state-ls.after and, similarly: cd tests/testsuite.dir/222 ls -l state-ls.before state-ls.after file state-ls.before state-ls.after diff -u state-ls.before state-ls.after diff state-ls.before state-ls.after _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
