QEMU 7.0 seems to trigger an issue with makensis which is used for 
building the QEMU installer for Windows: it terminates with different 
kinds to errors (SIGBUS, SIGSEGV and mmap related errors) depending on 
the details of the build environment.

I currently think that this is related to the total size of the 
installed components which exceeds 2 GiB. Maybe a 32 bit int value is 
used somewhere in makensis.

A simple workaround is removing /SOLID in qemu.nsi, but that increases 
the size of the installer significantly.

Stripping the executables might also help to stay below the critical size.

I'm sorry that I missed sending patches to add qemu-storage-daemon.exe 
to qemu.nsi and for some format strings in calls of vu_panic. I don't 
think those are critical for the release.

Kind regards,
Stefan
