            Bug ID: 54592
           Summary: Some binaries page-fault when run on "ihc" filesystem
           Product: Wine
           Version: 8.1
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs(a)winehq.org
          Reporter: hasezoey(a)gmail.com
      Distribution: ---

it seems like running some binaries from "ihc" results in page-fault, examples:

- ADE_2.0_Installer.exe runs just fine on "ihc"
- python-2.7.18.msi runs just fine on "ihc"
- python-3.9.0-amd64.exe page faults on "ihc"
- python-3.11.2-amd64.exe page faults on "ihc"
- VC_redist.x64.exe (14.34.31938) page faults on "ihc"
- customly compiled rust binary (msvc compiler) page faults on "ihc"

all the things listed above run just fine when run from "btrfs"

i have tried debugging my custom rust binary, and noticed that beyond some
point the data just seems to be repeating (see
https://forum.winehq.org/viewtopic.php?p=139841#p139841)

all tests were done with qemu, tested with Manjaro 22.0.3 and Linux Mint 21.1,
with wine 7.0.1, 8.0.0, 8.1.

ihc fstab entry: "ihc /run/media/shared trans=virtio,nobootwait,rw,_netdev 0 0"
qemu cmd line entry for virtfs: "-virtfs
local,path=./shared,mount_tag=ihc,security_model=mapped"
