Bug #: 28738 Summary: user32/tests: invalid read in server_end_to_end_callback in dde.ok? Product: Wine Version: 1.3.30 Platform: x86 OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: user32 AssignedTo: wine-bugs@winehq.org ReportedBy: dank@kegel.com Classification: Unclassified
Not sure how bad an invalid read in a dbgstr is, but here's the log:
Invalid read of size 2 at wine_dbgstr_wn (test.h:471) by server_end_to_end_callback (test.h:66) by WDML_InvokeCallback (dde_misc.c:734) by WDML_ServerHandle (dde_server.c:834) by WDML_ServerConvProc (dde_server.c:1112) by ???

--- Comment #1 from Dan Kegel dank@kegel.com 2011-10-15 23:05:23 CDT --- There are lots more, it's not just a debug print. e.g.
Invalid read of size 2 at strlenW (unicode.h:200) by CompareStringW (locale.c:2821) by lstrcmpW (locale.c:2976) by dde_server_wndprocW (dde.c:1424) by ??? (in user32.dll.so) by call_window_proc (winproc.c:242) by WINPROC_call_window (winproc.c:899) by DispatchMessageW (message.c:3809) by WDML_SyncWaitTransactionReply (dde_client.c:1069) by WDML_ClientHandle (dde_client.c:1126) by DdeClientTransaction (dde_client.c:1224) by test_dde_aw_transaction (dde.c:1613)
Invalid read of size 4 at WDML_GetConv (dde_misc.c:1989) by DdeQueryConvInfo (dde_misc.c:2194) by test_dde_aw_transaction (dde.c:1718)
Lots and lots of warning of that sort.

--- Comment #2 from Jeff L lats@yless4u.com.au 2011-10-20 05:46:19 CDT --- Dan, can you give me the config that you were running when the test failed. I have not been able to reproduce it running the dde test.

--- Comment #3 from Dan Kegel dank@kegel.com 2011-10-20 07:02:49 CDT --- Sorry, I should have mentioned that.
I'm running the test under valgrind-3.6.1 like this:
svn export https://winezeug.googlecode.com/svn/trunk/valgrind/valgrind-suppressions
VALGRIND_OPTS="--trace-children=yes --track-origins=yes \ --gen-suppressions=all --suppressions=`pwd`/valgrind-suppressions \ --leak-check=no --num-callers=30 --workaround-gcc296-bugs=yes \ --vex-iropt-precise-memory-exns=yes -v" export VALGRIND_OPTS WINETEST_WRAPPER="valgrind" export WINETEST_WRAPPER
make dde.ok > log.txt 2>&1
