Fortran 运行时错误“已修复"通过写输出 [英] Fortran runtime error "fixed" by writing output

问题描述

我在使用一些用于研究的旧代码时遇到问题，我想使用英特尔 Fortran 编译器进行编译.在一个特定的子例程中，我会遇到分段错误，除非我添加一个只输出循环索引值的 write 语句.

I've having trouble with some old code used for research that I would like to compile using the Intel Fortran compiler. In a particular subroutine, I get segmentation faults unless I add in a write statement that just outputs the value of the loop index.

do j=1,ne

SOME STUFF

write(*,*) 'j=', j

end

什么可能导致我的错误，以至于这个写语句可以修复我的分段错误?(注:j 声明为整数)

What could be causing my error such that this write statement would fix my segmentation fault? (Note: j is declared as an integer)

谢谢，凯利

推荐答案

导致此类错误的经典方法，通过插入 write 语句修复":

Classic ways of causing this type of error which is 'fixed' by inserting write statements:

1. 离开数组的末尾——使用你的编译器打开边界检查和调试选项来检查这个；

1. walking off the end of an array -- use your compiler to switch on bounds-checking and debugging options to check for this;

提供给子程序的参数与预期的参数不一致.同样，如果可能，请使用您的编译器，否则请使用您的眼睛.

disagreement between arguments provided to a sub-program and arguments expected. Again, use your compiler if possible, your eyes otherwise.

其中之一是原因的可能性是 5 比 1.

Odds are 5-to-1 that one of these is the cause.
