Build error of ASan-enabled AOSP 13 for x86_64 Cuttlefish

[Hoyoung Kim]

Hello, android-building!

I'm trying to build AOSP 13 for x86_64 Cuttlefish with ASan enabled.
I downloaded the source code of android13-gsi branch and selected aosp_cf_x86_64_phone-userdebug target.

However, the following linking error occurred during the building:
(Some logs were omitted to reduce the length, and here is the entire error message: https://www.dropbox.com/s/9qeeld4ouqjhu9s/full-log.txt)

ld.lld: error: too many errors emitted, stopping now (use -error-limit=0 to see all errors)
clang-14: error: linker command failed with exit code 1 (use -v to see invocation)
22:07:17 ninja failed with: exit status 1

#### failed to build some targets (13:02 (mm:ss)) ####
```

To reproduce the build failure:

```
# Download the source code
$ mkdir workspace
$ cd workspace
$ repo init -u https://android.googlesource.com/platform/manifest -b android13-gsi
$ repo sync

# Build without ASan - successful
$ . build/envsetup.sh
$ lunch aosp_cf_x86_64_phone-userdebug
$ m

# Build with ASan - the error occurs
$ export SANITIZE_TARGET=address m
```

Instead of Cuttlefish, I also tried the traditional emulator with android-13.0.0_r7 branch and aosp_x86_64-eng target.
However, the same ld.lld linking error occurred.

Can I get suggestions for using ASan in Cuttlefish?

Thanks!

I found a typo in my previous post.

Sorry for the confusion.

The problematic build command should be:

```

$ SANITIZE_TARGET=address m

```

not

```

$ export SANITIZE_TARGET=address m

```

I'm still trying to fix this build failure and any help would be highly appreciated!
