在我从事的一个项目中，我们使用从 Fortran 和f2py编译的 Python C 模块。我在 Windows 7 32 位（使用 mingw32）和基于 32 位 Linux 的服务器上构建它没有任何问题。但是我最近在我用于开发的笔记本电脑上安装了 Ubuntu 10.04 LTS 64bit，当我构建它时，我收到了很多警告（尽管我显然已经安装了所有 gcc/fortran 库/编译器），但它确实完成构建。但是，当我尝试在应用程序中使用内置模块时，它的大部分似乎运行良好，但随后它崩溃并出现错误：
* 检测到 glibc * /home/botondus/Envs/gasit/bin/python: free(): 下一个大小无效（快速）：0x0000000006a44760 ***
运行f2py -c -m module_name ./fortran/source.f90 时的警告

我尝试通过安装 gfortran multilib 软件包并使用 -m32 选项运行 f2py 来构建 32 位版本（但没有成功）：
f2py -c -m 模块名 ./fortran/source.f90 --f77flags="-m32" --f90flags="-m32"
关于我可以尝试构建 32 位版本或正确构建 64 位版本的任何建议？
编辑：看起来它在子程序结束时崩溃了。“写”执行得很好……这很奇怪。
write(6,*)'Eh=',Eh
end subroutine calcolo_involucro
完整的回溯很长，我不确定它是否有帮助，但这里是：
