Zig Version
0.14.1
Steps to Reproduce and Observed Behavior
I hit a segmentation fault during zig build. Unfortunately, isolating the issue is tricky, so I hope this is sufficient to locate the issue. I might be able to provide some specific details upon request. Note the debug trace was generated with the current bootstrap version.
error: thread 2896706 panic: reached unreachable code
