Bug #: 29378 Summary: Non-aligned pointer being freed (MacOS) seconds after an app exits Product: Wine Version: 1.3.26 Platform: x86 OS/Version: Mac OS X Status: NEW Severity: normal Priority: P2 Component: wineserver AssignedTo: wine-bugs@winehq.org ReportedBy: hoehle@users.sourceforge.net Classification: Unclassified
On MacOS, I observe random occurrences of malloc: *** error for object 0x402086a0: Non-aligned pointer being freed (2) *** set a breakpoint in malloc_error_break to debug after an app exits.
A message like that has been mentioned in bug #28291, bug #22722 or bug #21655, comment #4 and bug #28039, comment #6. I don't know if the cause is always the same.
I once thought it may be caused by audio but it's not. It currently presents itself as follows: the message appears a few seconds after an app (e.g. winecfg) exits, thus I believe it's in the server (it might be one of the services). Not every call to winecfg terminates with that message.
Using WINEDEBUG=+coreaudio I observed that it can appear after winecfg even when not clicking the audio tab, thus audio is loaded and not the cause.
Setting a breakpoint doesn't help:

--- Comment #1 from Jörg Höhle hoehle@users.sourceforge.net 2011-12-18 09:13:57 CST --- I've not seen that error once in 50 runs when using: WINEDLLOVERRIDES=services.exe= wine winecfg and only once with: WINEDLLOVERRIDES=plugplay.exe= wine winecfg The former prevents the Drives tab from working.
The normal process list is: loader/wine C:\windows\system32\explorer.exe /desktop loader/wine C:\windows\system32\plugplay.exe loader/wine C:\windows\system32\winedevice.exe MountMgr loader/wine C:\windows\system32\services.exe server/wineserver loader/wine winecfg
Note that I had X11 up and running all the time. Might well be a race condition.

--- Comment #3 from Jörg Höhle hoehle@users.sourceforge.net 2011-12-20 16:26:16 CST --- I run $ server/wineserver -f in one shell and $ wine -h in another The malloc message appears in the wine shell at the moment wineserver exits in the first shell.

--- Comment #4 from Vitaliy Margolen vitaliy-bugzilla@kievinfo.com 2011-12-20 20:29:34 CST --- Wineserver shouldn't exit right away, but with some pause. Can you run server under debugger? Or at least look at +relay,+tid,+seh,+server log for any clues?

Wineserver shouldn't exit right away, but with some pause.
Indeed. I wasn't precise enough: Shell_1$ server/wineserver -f Shell_2$ wine -h wine -h exits immediately without malloc message -- yet.
~2 seconds later, the malloc message appears in shell_2. At the same time, the prompt returns in shell_1.

--- Comment #6 from Jörg Höhle hoehle@users.sourceforge.net 2013-03-02 17:24:48 CST --- FWIW, I have not seen this message when booting Snow Leopard 10.6.8 on the same machine. The configuration is different too. On Snow Leopard, I use the original Apple X11, which is older than the XQuartz 2.6.3 that I use with the Leopard 10.5.8 partition, according to their release notes.

--- Comment #7 from Austin English austinenglish@gmail.com --- This is your friendly reminder that there has been no bug activity for over 700 days. Is this still an issue in current (1.7.36 or newer) wine?
