Bug ID: 54927
           Summary: grepwinNP3 (part of Notepad3) crashes inside uxtheme
           Product: Wine
           Version: 8.7
          Hardware: x86-64
               URL: https://github.com/rizonesoft/Notepad3/releases/downlo
                    ad/RELEASE_6.23.203.2/Notepad3_6.23.203.2_x64_Setup.ex
                    e
                OS: Linux
            Status: NEW
          Keywords: download, source
          Severity: normal
          Priority: P2
         Component: uxtheme
          Assignee: [e-mail]
          Reporter: [e-mail]

This is a kind of "grep with GUI":

Unhandled exception: page fault on read access to 0x0000000000000004 in 64-bit
code (0x0000006d5089f5).

=>0 0x0000006d5089f5 DrawThemeTextEx+0x45(hTheme=000000000025CA20,
hdc=0000000001410094, iPartId=0x2, iStateId=0, pszText=L"Regex search",
iCharCount=0xffffffff, flags=0x2450, rect=00000000001FC400,
options=0000000000000000)
[/home/louis/sda2/wine64-build/../wine/dlls/uxtheme/draw.c:1790] in uxtheme
(0x000000001fc400)

Apparently crashes in next line because "options" pointer is NULL:

if (options->dwFlags & ~(DTT_TEXTCOLOR | DTT_FONTPROP))
        FIXME("unsupported flags 0x%08lx\n", options->dwFlags);

uxtheme: Add a NULL check for options parameter in DrawThemeTextEx().

Does this patch help?

For your reference, the code which calls DrawThemeTextEx with nullptr is no
longer used. See the commit which imports a latest release from grepWin,
