在我参与的一个项目中，我们使用了一个用f2py从Fortran编译的Python C模块。我在Windows 7 32位系统上（使用mingw32）构建这个模块时没有遇到任何问题，在服务器上它也能在32位Linux上顺利构建。不过，最近我在我的开发用笔记本上安装了64位的Ubuntu 10.04 LTS，当我尝试构建时，出现了很多警告（尽管我似乎已经安装了所有的gcc/fortran库和编译器），但构建还是完成了。然而，当我在应用程序中使用这个构建好的模块时，大部分功能运行得不错，但最后却崩溃了，出现了一个错误：

* glibc 检测到 * /home/botondus/Envs/gasit/bin/python: free(): invalid next size (fast): 0x0000000006a44760 ***

运行 f2py -c -m module_name ./fortran/source.f90 时出现的警告：

我尝试通过安装gfortran的多库包来构建一个32位版本，并使用-m32选项运行f2py（但没有成功）：

f2py -c -m module_name ./fortran/source.f90 --f77flags="-m32" --f90flags="-m32"

有没有什么建议可以让我尝试构建32位版本或者正确构建64位版本呢？

编辑: 看起来崩溃发生在一个子程序的最后。'write'执行得很好……这很奇怪。

     write(6,*)'Eh=',Eh

end subroutine calcolo_involucro

完整的回溯信息很长，我不确定这是否有帮助，但我还是把它贴出来：

幸运的是，我终于解决了这个问题。看起来我没有注意到，在Ubuntu 10.04的库里，numpy这个包的版本只有v1.3.0。我先把numpy卸载了，然后从源代码编译了v1.4.1的版本。之后重新运行f2py时还是出现了同样的警告，不过使用这个模块就不再崩溃了。
