我有这个代码段,我打开/关闭文件多次(在一个循环中)：
for(i=1;i<max;i++)
{
/* other code */
plot_file=fopen("all_fitness.out","w");
for (j=0;j<pop_size;j++)
fprintf(plot_file,"%lf %lf\n",oldpop[i].xreal[0],oldpop[i].obj);
fclose(plot_file);
/*other code*/
}@H_403_3@
我在这里得到一个SIGABRT,并附带以下回溯：

行号1100,是我在上述代码段中执行fclose()的行.上述行为的原因是什么？任何指针都不胜感激.
(我在Linux上使用gcc)
