            Bug ID: 112353
           Summary: asan-enabled, aarch64-gcc cross-compiled elf
                    executables fail ro run in qemu-user on x86
           Product: gcc
           Version: 12.3.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: sanitizer

  Target Milestone: ---

On Ubuntu 23.04 x86_64, an aarch64 cross-compiled elf executable with Addre=
ss
Sanitizer (asan) enabled, fails with the run-time error:
```
AddressSanitizer: CHECK failed: asan_poisoning.cpp:38 "((AddrIsInMem(addr))=
) !=3D
(0)" (0x0, 0x0) (tid=3D1909)
    <empty stack>
```

This might be related to qemu and not gcc, but it reproduced also with gcc
13.2.0, but not with gcc 11.4.0.

Versions used:

```
$ aarch64-linux-gnu-g++ --version
aarch64-linux-gnu-g++ (Ubuntu 12.3.0-1ubuntu1~23.04) 12.3.0

$ qemu-aarch64-static -version
qemu-aarch64 version 7.2.0 (Debian 1:7.2+dfsg-5ubuntu2.3)
```

Steps to reproduce:
```
$ echo "int main() {return 1;}" > /tmp/poc.cpp
$ aarch64-linux-gnu-g++ -fsanitize=3Daddress /tmp/poc.cpp -o /tmp/poc=20
$ qemu-aarch64-static /tmp/poc ## this takes a while
AddressSanitizer: CHECK failed: asan_poisoning.cpp:38 "((AddrIsInMem(addr))=
) !=3D
(0)" (0x0, 0x0) (tid=3D2220)
    <empty stack>
