I've replaced every memcpy() in kernel32/process.c to memcpy_unaligned() and it
fixed munged paths - I do not get complaints about L"dows\\syste\\syswow64"
anymore. But heap corruption is still present.

Then I began to remove '_unaligned' suffix and see where munged paths show
themselves.
It turns to be a 965 line. This code works:

964:        memcpy( buffer, DIR_Windows, len * sizeof(WCHAR) );
965:        memcpy_unaligned( buffer + len, default_syswow64W,
sizeof(default_syswow64W) );
966:        DIR_SysWow64 = buffer;

and this not:

964:        memcpy( buffer, DIR_Windows, len * sizeof(WCHAR) );
965:        memcpy( buffer + len, default_syswow64W, sizeof(default_syswow64W)
);
966:        DIR_SysWow64 = buffer;
