Hi swift team,
I download the prebuilt swift 4.0 from here
<https://swift.org/builds/swift-4.0-release/ubuntu1404/swift-4.0-RELEASE/swift-4.0-RELEASE-ubuntu14.04.tar.gz>
and
try to do some work on the generated LLVM BC. However, I got a seg fault
when running the binary executable compiled from bitcode as shown below:
$ cat hello.swift
print("Hello World")
$ swiftc hello.swift -emit-bc -o hello.bc
$ clang++ hello.bc -c -o hello.o
$ swiftc hello.o -o hello
$ ./hello
Segmentation fault (core dumped)
It works fine if no bitcode file is involved here.
$ swiftc hello.swift -c -o hello.o
$ swiftc hello.o -o hello
$ ./hello
Hello World
I am running Ubuntu 14.04.3 (kernel 4.8.0). I also encountered the same seg
fault if I use the prebuilt swift 3.1.1
Is it the right way to compile the bitcode generated from swift? Or is it a
bug in swift ?
Thanks a lot in advance!
Best regards,
Jeffrey
