If I compile the program below with shared libraries, it works fine. If I add
"-static" to the command line, it dies with a segfault:
#include <stdio.h>
#include <pwd.h>
int main(int argc, char **argv)
{
struct passwd *pwdptr;
int uid;
uid = getuid();
pwdptr = getpwuid(uid);
printf("uid = %d, name = %s\n", uid, pwdptr->pw_name);
}
gigan:~/src> cc -o pwdtest pwdtest.c
gigan:~/src> pwdtest
uid = 1000, name = gobbel
gigan:~/src> cc -static -o pwdtest pwdtest.c
gigan:~/src> pwdtest
Segmentation fault
getuid seems to be doing the right thing, but getpwuid always returns 0 in the
statically-linked library.
