`swift build --configuration release` causes Linux VM to crash

[progressive-galib]

---

The bug
Building the project in debug mode works fine. However, attempting to build in release mode (swift build --configuration release) causes the entire WSL2 VM to abruptly crash. The terminal session is terminated, and no specific error message is provided except a compile failure with signal 9.

---

To Reproduce
Steps to reproduce the behavior:

1. Clone the repository:

   git clone https://github.com/stackotter/swift-bundler
   cd swift-bundler

2. Attempt to build in release mode:

   swift build --configuration release

3. Observe that the VM crashes or restarts during the build (typically near the end of the compilation process).

You can now close this terminal with Ctrl+D, or press Enter to restart.

Expected behavior
The build should either complete successfully or fail gracefully. It should not cause the WSL2 VM to crash.

Environment (please complete the following information):

• OS: Windows 10 with WSL2
• Distro: fedora remix on WSL2
• Swift version:

galib@galib:/mnt/c/Users/mahfu/Desktop/nf/swift-bundler$ swift --version
Swift version 6.1.2 (swift-6.1.2-RELEASE)
Target: x86_64-unknown-linux-gnu

I have noticed release builds of Swift Bundler taking a pretty astronomically long time sometimes, which is probably related to this. That said, I’ve never had it crash a VM! Could be RAM usage related? This is definitely something I’ll need to investigate
