Navdeep, thank you for the debugging information (provided out-of-band). The problem seems to be with leaving a variable uninitialized when a cross-device rename is detected and then accessing that variable before checking the error code. Also, thank you for testing a fix. I'll commit it very soon. -- Andriy Gapon _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
