Summary: Deallocation of a pointer not malloced
Product: rsync
Version: 3.0.6
Platform: PPC
OS/Version: Mac OS X
Status: NEW
Severity: major
Priority: P3
Component: core
AssignedTo: wayned at samba.org
ReportedBy: aaro at iki.fi
QAContact: rsync-qa at samba.org
(The OS version is Mac OS X 10.4.11 with all updates as of today and rsync is
compiled with Apple's gcc powerpc-apple-darwin8-gcc-4.0.1 (build 5370).)
When I'm running rsync with the following options:
-X -a -v -n --exclude-from=... --delete --backup --backup-dir=...
I occasionally get the following errors from the Mac OS X malloc():
rsync(486) malloc: *** Deallocation of a pointer not malloced: 0x4aeb54; This
could be a double free(), or free() called with the middle of an allocated
block; Try setting environment variable MallocHelp to see tools to help debug
It can be reproduced with dry runs. But if the file system is modifed, it can
also go away.
The stack trace from where the printout comes (strings replaced with "..."):
