tmpnam() core dumping

[Bill Ahlbrandt <bahlbr@icdata.com>]

I am getting a core dump when I use the tmpnam() function.

I'm running slackware 2.0.29, 

gcc -v gives:

Reading specs from /usr/local/lib/gcc-lib/i486-pc-linux-gnulibc1/egcs-2.90.21/specs
gcc version egcs-2.90.21 971202 (egcs-1.00 release)

This probably has nothing to do with egcs, but being extremely new this environment and compiler, any assistance will be much appreciated.

Note that the tempnam function works just fine.


The following code produces the output that follows:

#include <stdio.h>

int main() {
  char *tempFileName;
  printf("doing tempnam\n");
  tempFileName=tempnam(".","xxx");
  printf("done\n");
  if (tempFileName) {
    printf("I got %s\n",tempFileName);
  } else {
    printf("Got an error\n");
  } /* endif */

  printf("doing tmpnam\n");
  tempFileName=tmpnam("xxx");
  printf("done\n");
  if (tempFileName) {
    printf("I got %s\n",tempFileName);
  } else {
    printf("Got an error\n");
  } /* endif */
  return 0;
}

Thanks in advance.
