--- Comment #4 from xantares <xantares09 at hotmail.com> ---
I failed to report that I was running it from a docker image (usually it
behaves the same).

FROM archlinux:latest
RUN echo -e "[multilib]\nInclude = /etc/pacman.d/mirrorlist" >>
/etc/pacman.conf
RUN pacman -Sy wine mingw-w64-gcc strace --noconfirm
WORKDIR /tmp
ADD main.c /tmp
RUN x86_64-w64-mingw32-gcc main.c
ENV WINEARCH=win64
RUN wine a.exe

I noticed that if I run it with the 64 bits exe right away it goes fine
(something wrong with the preloader code ?):

RUN wine64 a.exe

if I run it with strace I notice that some mmap call fails:

mmap2(NULL, 65536, PROT_NONE,
MAP_PRIVATE|MAP_FIXED|MAP_ANONYMOUS|MAP_NORESERVE, -1, 0^[[0m^[[91m) = -1 EPERM
(Operation not permitted)

Actually this problem is a regression in 7.5 from 7.4 as another 7.3 bug fixed
in 7.4 was hiding it:
