[MinGW] Strange behaviour with C structures initialisation #6

Open GunGraveKoga opened 7 years ago

GunGraveKoga commented 7 years ago

Windows structure WIN32_FIND_DATA:

typedef struct _WIN32_FIND_DATA {
  DWORD    dwFileAttributes;
  FILETIME ftCreationTime;
  FILETIME ftLastAccessTime;
  FILETIME ftLastWriteTime;
  DWORD    nFileSizeHigh;
  DWORD    nFileSizeLow;
  DWORD    dwReserved0;
  DWORD    dwReserved1;
  TCHAR    cFileName[MAX_PATH];
  TCHAR    cAlternateFileName[14];
} WIN32_FIND_DATA, *PWIN32_FIND_DATA, *LPWIN32_FIND_DATA;

If I try to init this structure inside swift code like this:

let win_find_data = WIN32_FIND_DATA()

I get output:

$ swift -v -I. ./main.swift
Swift version 3.0-dev (LLVM 449f1d0641, Clang 0ebffe65d9, Swift 9555952109)
Target: x86_64-w64-windows-gnu
"C:\\msys64\\swift\\bin\\swift.exe" -frontend -interpret ./main.swift -target x86_64-w64-windows-gnu -disable-objc-interop -I . -color-diagnostics -module-name main
Segmentation fault

If I use name of structure with underscore

let win_find_data = _WIN32_FIND_DATA()

I get:

Thanks for your report. Could you tell me the imported module and the full source of main.swift ?

tinysun212 commented 7 years ago

This is my test source in Cygwin.

$ cat main.swift
import CWin32

let win_find_data = WIN32_FIND_DATA()
print(win_find_data)

$ cat Package.swift
import PackageDescription

let package = Package(
    name: "Issue6",
    dependencies: [
        .Package(url: "https://github.com/tumasgiu/CWin32.git", majorVersion: 1, minor: 0)
    ]
 )

To build with the Swift Package Manager, Cygwin needs some more options (Sadly, the swiftpm is not yet ported for MinGW.)

I think @tumasgiu 's CWin32 module will be helpful (or good reference) for MinGW version.

GunGraveKoga commented 7 years ago

Source code of my main.swift is similar to yours cygwin test. I use CWin32 too, and on cygwin it hasn't errors, only on mingw. Actually I get error even if used my own C structure, similar to WIN32_FIND_DATA, defined in CWin32.h header

tinysun212 commented 7 years ago

Could you try this again with the latest Swift compiler for MinGW-w64?

tinysun212 commented 6 years ago

Could you try this again with the latest compiler? This issue is very similar to SwiftForWindows/SwiftForWindows#32.

tinysun212 commented 6 years ago

ping?
