[Bug c/19089] New: Environment variable TMP may yield gcc: abort with internal error

["m at verified dot de" <gcc-bugzilla at gcc dot gnu dot org>]

When a (bash) environment variable TMP is set to a file with execution
rights 0755, gcc aborts with an internal error. E.g.:

# -- bash shell --------------------------------------------------------------
$ uname -a
CYGWIN_NT-5.1 DF8JLP0J 1.5.5(0.94/3/2) 2003-09-20 16:31 i686 unknown unknown Cygwin
$ gcc --version

$ cat a.c

#include <stdlib.h>
#include <stdio.h>
int main(int argc , char *argv[]){
  printf("Ok.\n");
  return 0;
}
$ unset TMP
$ gcc -save-temps a.c
$ touch /tmp/file.txt
$ export TMP=/tmp/file.txt
$ gcc -save-temps a.c
$ chmod u+x /tmp/file.txt
$ gcc -save-temps a.c
$ chmod 0755 /tmp/file.txt 
$ gcc -save-temps a.c
gcc: Internal error: Aborted (program collect2)

## ----------------------------------------------------------

The MAN page does not note a dependency to TMP (only TMPDIR) ist listed.
