See https://test.winehq.org/data/patterns.html#scrobj:scrobj
This crash does not happen when running scrobj:scrobj on its own. I determined
that the source of interference is advapi32:registry.
It is the combination of test_reg_open_key() and test_classesroot() in
registry.c that causes the crash. More specifically this call in
test_classesroot():
res = RegCreateKeyExA( HKEY_LOCAL_MACHINE,
"Software\Classes\WineTestCls", 0, NULL, REG_OPTION_NON_VOLATILE,
                           KEY_ALL_ACCESS, NULL, &hklm, NULL );
