Bug ID: 35229 Summary: Demo version of Freehand 9 hangs at Intro window Product: Wine Version: 1.7.9 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: bugs.drew@yahoo.com Classification: Unclassified

There is a windowing problem in Freehand 9 (circa 2000) that I would like to report, but the demo version doesn't allow the program to get that far.

When freehand9-trial.exe is installed in a clean prefix, it appears to install successfully despite a lot of FIXMEs. The when launching the program (pressing the "Try" button on the opening window, the windows disappears the Freehand is not launched.

The only console messages occur before pressing the "Try" button and are :

wine: Unhandled stack overflow at address 0xb74439fa (thread 000d), starting debugger... err:seh:setup_exception_record stack overflow 1184 bytes in thread 000d eip 7bc61404 esp 00240e90 stack 0x240000-0x241000-0x340000

Curiously, these messages also appear when launching any other program (e.g. winecfg) from this prefix, but not from a clean one.

The file "freehand9-trial.exe" can be downloaded from: http://macromedia-freehand.software.informer.com/download/

Its sha1sum is a502e0d2e4590e118ea0215e947f16913a57b938

--- Comment #2 from Anastasius Focht focht@gmx.net --- Hello folks,

confirming. Brain damaged app code ... as expected from Adobe/Macromedia :|

Relevant part of trace log:

The main thread creates several windows (toolwindow -> hidden!, dialog, ...) and a secondary thread. One of the first actions of this secondary thread is calling ShowWindow( toolWindow, SW_HIDE) which gets synchronized via SendMessage() to the main thread because it owns the window.

Unfortunately after spawning the secondary thread, the main thread immediately calls Sleep(5000) and live-loops a register, blocking the secondary thread indefinitely (which still hangs in SendMessage because the main thread doesn't pump messages).

The actual code of main thread (disassembly after attaching to hanging process):

--- snip --- ... 00401E4F 52 PUSH EDX ; pThreadId 00401E50 890D DC0B4500 MOV DWORD PTR DS:[450BDC],ECX 00401E56 890D E00B4500 MOV DWORD PTR DS:[450BE0],ECX 00401E5C 51 PUSH ECX ; CreationFlags => 0 00401E5D 51 PUSH ECX ; Parameter => NULL 00401E5E 68 F0184000 PUSH 004018F0 ; StartAddress = 0x4018F0 00401E63 51 PUSH ECX ; StackSize => 0 00401E64 51 PUSH ECX ; pSecurity => NULL 00401E65 890D E40B4500 MOV DWORD PTR DS:[450BE4],ECX 00401E6B FF15 38D14200 CALL DWORD PTR DS:[<&KERNEL32.CreateThread 00401E71 68 88130000 PUSH 1388 ; Time = 5000 ms 00401E76 A3 38B14300 MOV DWORD PTR DS:[43B138],EAX 00401E7B FF15 7CD04200 CALL DWORD PTR DS:[<&KERNEL32.Sleep>] 00401E81 A1 D80B4500 MOV EAX,DWORD PTR DS:[450BD8] 00401E86 85C0 TEST EAX,EAX 00401E88 74 FC JZ SHORT 00401E86 00401E8A 68 88130000 PUSH 1388 ; Timeout = 5000 ms 00401E8F 50 PUSH EAX ; hProcess => [450BD8] = NULL 00401E90 FF15 8CD24200 CALL DWORD PTR DS:[<&USER32.WaitForInputId 00401E96 E8 A5040000 CALL 00402340 00401E9B 59 POP ECX 00401E9C C3 RETN --- snip ---

Notice the 'live' loop on register value at 00401E88..00401E88. The compiler is not at fault here. Whoever wrote that code probably never heard of 'volatile' (the value of 0x450BD8 is set some time later from secondary thread).

Anyway, Wine needs to check first if the 'show' command turns out a no-op, not involving any message handling to avoid the potentially blocking SendMessage() to the thread owning the window.

return SendMessageW( hwnd, WM_WINE_SHOWWINDOW, cmd, 0 ); } --- snip ---

--- Comment #3 from Anastasius Focht focht@gmx.net --- Hello folks,

this is actually a dupe of bug 11582 which I already analyzed some years ago, though missing the SW_HIDE on already hidden (tool)window (=no-op) part.

Regards
