Bug#882602: ocaml-mingw-w64: create bytecode shared objects that makes C programs using it to segfault
Package: ocaml-mingw-w64
Version: 4.01.0~20140328-1+b2
Severity: normal
I am trying to produce libraries usable from C with OCaml and to compile them
using CMake, for which I created a module that tries to simplify this process
[1].
As part of the CMake module for building C libraries with OCaml, I have
automated the building of a few combinations of options [2].
Among those combinations, cross-compiling for Windows with currently packaged
x86_64-w64-mingw32-ocamlopt and i686-w64-mingw32-ocamlopt is producing some
unusable binaries [3] [4].
Using opam-cross-windows [5], with the same C compiler, does not pose the same
issue [2].
In order to reproduce the issue you can perform the following steps:
git clone https://github.com/giuliopaci/ocaml-cmake.git
cd ocaml-cmake
mkdir build
cd build
cmake ../examples/hello_world_lib -DCMAKE_VERBOSE_MAKEFILE=on
-DCMAKE_TOOLCHAIN_FILE=../toolchains/Toolchain-mingw32.cmake
make
wine ./main-libhelloworld-bytecode.exe
