According to Bruce Dugan on 12/1/2008 1:19 AM: Hi Bruce, > This problem has been resolved. I traced the errors to m4. The README > for m4 stated that the libsigsegv libraries were optional. Apparently > for Mac OS 10.5 they are not. I'm glad that using libsigsegv seemed to resolve your problem. However, the presence of libsigsegv is supposed to be optional: its presence should only affect behavior on the corner case of stack overflow, and not normal runs where m4 is expected to run to completion. I seriously doubt that it was the recompilation of m4 that changed your results, and suspect that you could still get the autoconf testsuite to pass even without a libsigsegv-enabled m4. But in looking further at your log, I seriously doubt that it was m4, and rather, it was an intermittent OS bug that you ran into. All three of your reported failures look somewhat like this: ./torture.at:31: $at_diff "state-ls.before" "state-ls.after" - --- /dev/null 2008-11-30 21:13:21.000000000 -0800 +++ /Users/bruce/OSF_GNU_Software/LIVES-src_and_lib/LIVES-prereqs/autoconf/autoconf-2.63/tests/testsuite.dir/at-groups/147/stdout 2008-11-30 21:13:21.000000000 -0800 @@ -0,0 +1,7 @@ +--- state-ls.before 2008-11-30 21:13:21.000000000 -0800 ++++ state-ls.after 2008-11-30 21:13:21.000000000 -0800 +@@ -5,3 +5,4 @@ + configure.ac + install-sh + testsuite.log ++testsuite.log This is the comparison of two compared directory listings, where one of the two listings shows testsuite.log twice. In other words, you are tickling a well-known Mac bug where readdir() sometimes returns the same file more than once, which breaks the diff. I'm wondering if we should beef up the autoconf testsuite to filter ls output through uniq in order to quit tickling this Mac bug, as there have been quite a few reports of autoconf testsuite failures due to this rather unrelated OS bug. - -- Don't work too hard, make some time for fun as well!
