Error: fatal error encountered while reading from module 'Doggie'

[SusanCheng]

I'm trying put my library to the Google Cloud Platform, and here are the compiler crash log.

Here is the problem, my server should have two executables as result. First one is main server app and the second is svg_generator.
the lines show that the svg_generator build successful which's only rely on my library.

[66/70] Compiling Swift Module 'svg_generator' (20 sources)
[67/70] Linking ./.build/x86_64-unknown-linux/release/svg_generator

that means the Module App having a crash with my library and vapor.

I'm trying to solve this first.

[johannesweiss]

That is a compiler crash and hence a Swift compiler bug. If you wouldn’t mind, filing a bug report on bugs.swift.org would be much appreciated.

[SusanCheng]

I’m trying to reproduce the bug but it seems difficult.

[SusanCheng]

Done!!

I create a package to reproduce the bug.

I got it!!!

I found same function in swift-nio 1.13.2 which crash the compiler

extension Data: ContiguousCollection {
    @_inlineable
    public func withUnsafeBytes<R>(_ body: (UnsafeRawBufferPointer) throws -> R) rethrows -> R {
        return try self.withUnsafeBytes { (ptr: UnsafePointer<UInt8>) -> R in
            try body(UnsafeRawBufferPointer(start: ptr, count: self.count))
        }
    }
}
