Summary: King's Quest Collection Series (1997): setup.exe
crashes
Product: Wine
Version: 1.3.7
Platform: x86-64
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: -unknown
AssignedTo: wine-bugs at winehq.org
ReportedBy: tristan_schmelcher at alumni.uwaterloo.ca
When attempting to install the game King's Quest Collection Series (the 1997
edition), setup.exe crashes partway through the installation. It happens every
time and always at the same place.
After debugging, I have determined that the problem is caused by incorrect
stack cleanup code in the 16-bit DDEML DLL. A number of functions in the .spec
file specify HSZ argument values as occupying one word on the stack, but in
fact they are a double word. As a result the stack cleanup code does not
increment the stack pointer by enough, so upon return the calling code's stack
pointer is not restored to the correct value.
I have attached a patch that changes the type of all HSZ arguments in the spec
to "long", which fixes the bug. (I will submit it to wine-patches too.)
