terminal output

ccsetup324.exe
md5: 63871c34f72f2f1f2fba4b5397686abb

I came across the problem when attempting to install the freeware version of
CCleaner v3.24 in Wine 1.5.16. I downloaded the installer (ccsetup324.exe) in
my ~/Desktop directory and launched the installer from that location. I can get
past the first couple of screens (language selection, EULA, install options),
but Wine crashes before the next page could appear(where the installer offers
to also install Google Chrome).
What's odd is that the crash happens only when the installer is launched from
certain directories in my /home. Such example is ~/Desktop or the root of my
/home.
Most of the directories in my /home don't trigger the crash and the installer
can get past that screen without crashing.
I must add that the crashes are consistent: launching the installer from a
certain directory always results in the crash.

If I start the installer with
WINEDEBUG=warn+heap wine ccsetup324.exe
then the crash doesn't happen and the following message is added to the
terminal output (just before the problematic screen appears):
>err:heap:HEAP_ValidateInUseArena Heap 0x110000: block 0x123f70 tail overwritten at 0x123fc0 (byte 0/8 == 0x00)

I found that the problem didn't occur with Wine 1.5.14, and reverting the
following commit on 1.5.16 resolves the crash:
40b01c1bfc6635775c2a13485d31340062423356 is the first bad commit

Let me know if you need further logs with specific debug channels enabled (in
case you can't reproduce the problem)
