Summary: --del (+old protocol?) sometimes leads to "double free"
crashes
Product: rsync
Version: 3.0.4
Platform: x64
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P3
Component: core
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
QAContact: [EMAIL PROTECTED]
It seems to depend on the file list to be synchronised, but sometimes, I get a
detection by glibc of a double free. If I remove "--del" (or "--delete") from
the arguments, all goes smoothly. For a given file list, it always happens, or
never happens. This is on a x86-64 and the other side is rsync 2.6.9, 32bits.
Trying with a different host having rsync 3.0.3 64bits, it goes fine.
Example:
rsync --archive --recursive --del --files-from=/home/piel/.autosync/lan/list
--exclude-from=/home/piel/.autosync/lan/exclude --cvs-exclude --verbose
/home/piel/ '[EMAIL PROTECTED]:~/backup-dutifh/'
