Executables and source code to help reproducing the problem

Hello,

I created a dll with a shared section (C language, Visual Studio 2013) and a
program to load it (Pascal language, Delphi 10.3.2).
If I run it with Wine64 (4.17) under macOS 10.15 Catalina I receive:
003b:err:virtual:map_file_into_view failed to set PROT_EXEC on file map, noexec
filesystem?
003b:err:module:map_image Could not map shared section .sdata

and in the system log I can read
Library load
(/private/tmp/.wine-1604910507/server-1000004-86265/anonmap.0NtRsH) rejected:
library load disallowed by system policy

So this is very similar to what happens with CEF, except that with CEF I don't
have this message:
003b:err:module:map_image Could not map shared section .sdata

So is there something else that a shared section in a library that can make
wineserver generate and load a library like
/tmp/.wine-1604910507/server-1000004-86265/anonmap.0NtRsH ?

Regards,

Michel Terrisse
