And here comes the resolution of the puzzle. Remember when I claimed there are no special flags set in the first mail? Except one flag that is actually true. ;) I did have a special flag set, which is CC = /usr/lib/gcc-snapshot/bin/gcc which is using the latest snapshot of the gcc compiler gcc (Ubuntu 20140405-0ubuntu1) 4.9.0 20140405 (experimental) [trunk revision 209146] instead of the standard install gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2 on my machine Using the standard compiler git build ands tests t5570,8 just fine in various versions. If I take the latest snapshot of gcc, I have a flakey behavior in Git versions ranging from current origin/master back to v2.0.0 (did not test further) Could somebody try to reproduce the failing test using the latest gcc snapshot compiler? -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
