Hallo,
while dealing with PR ports/157274 [1], I found that the following
program cause a segmentation fault on 7.3-RELEASE amd64, even though
my understanding of the man page of fdopendir(3) says it should not.
#include <fcntl.h>
#include <sys/types.h>
#include <dirent.h>
int main(int argc, char **argv) {
DIR *dirp;
int fd;
fd = open(".", O_RDONLY);
dirp = fdopendir(fd);
(void) readdir(dirp);
}
Compiling gives the warning "assignment makes pointer from integer without a
cast"
refering to the line with the fdopendir call. Indeed, adding the prototype
extern DIR *fdopendir(int);
right after the #include lines solves this problem. Is my understanding of the
man page that the above #include lines should suffice incorrect? Is this
problem known---or even fixed already?
I have reports that indicate that this problem also seems to exist on
7.3-RELEASE-p4 amd64
and 8.1-RELEASE i386. The above program does not segfault on my 8.2-STABLE
amd64.
Any hints on the status of this observation are very welcome.
Best regards,
Klaus
