Bug ID: 52118
           Summary: The 64-bit crypt32:store test crashes due to heap
                    corruption
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: crypt32
          Assignee: [e-mail]
          Reporter: [e-mail]

The 64-bit crypt32:store crashes due to heap corruption:

crypt32:store:0224 done (-1073740940) in 0s
Test failed: crash (c0000374)

https://test.winehq.org/data/patterns.html#crypt32:store

The crashes only happen with the 64-bit build. They happen almost
systematically on the TestBot's w864 VM and cw-rx460. It looks like the same
crash happens on the TestBot's Windows 10 1507, 1607 and 2009 VMs.

At least on cw-rx460 the crash happens around the last CertCloseStore(store,
0); call in testRegStoreSavedCerts(). Adding traces changes the crash location
a bit.

Also the test tends to crash every other time. That suggest there is some
cleanup issue.

--- Comment #1 from François Gouget  ---
The crash can also take other forms but the root cause is probably still the
same:

2022-04-27 and 2022-05-04 on w1064v1607
store.c:392: Test failed: Create cert context failed at 1, c0000005
store.c:392: this is the last test seen before the exception
107c:store: unhandled exception c0000005 at 00007FFC5A28E29E
crypt32:store:107c done (-1073741819) in 0s
Test failed: crash (c0000005)

2022-05-03 on w864 and 2022-06-01 on w1064v1607
store.c:454: this is the last test seen before the exception
09f8:store: unhandled exception c0000005 at 00007FFC5CFB9998
crypt32:store:09f8 done (-1073741819) in 0s

This crash can also happen on Windows 10 21H2. So it's best to consider that
all Windows versions can be impacted.
