The following very simple program segfaults in opendir when compiled with
-mno-cygwin but runs OK when not compiled with -mno-cygwin. I tried with
both gcc 2.95.3-1 and gcc 2.95.3-2.
/* File test_dir.c **********************************************************/
#include <stdlib.h>
#include <stdio.h>
#include <dirent.h>
int main (int argc, char *argv[])
{
DIR *dir;
struct dirent *dp;
if (argc<2) {
printf("test_dir directory\n");
return 1;
}
dir = opendir(argv[1]);
if (dir==NULL) {
printf("Error opening directory %s\n", argv[1]);
return 2;
}
for (dp=readdir(dir); dp!=NULL; dp=readdir(dir)) {
printf("\t%s\n", dp->d_name);
}
return 0;
}
/****************************************************************************/
When compiled with -mno-cygwin, if the directory given as an argument to
the program does not exist, opendir returns NULL as it should. If the
directory does exist, for example ".", opendir segfaults.
