             Bug #: 14438
           Summary: $TMPDIR not respected
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek at apple.com
        ReportedBy: peeter.joot at gmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


scan-build contains the following:

sub GetHTMLRunDir {
...
  if (!defined $Dir) {
    if (`uname` =~ /Darwin/) {
      $Dir = $ENV{'TMPDIR'};
      if (!defined $Dir) { $Dir = "/tmp"; }
    }
    else {
      $Dir = "/tmp";
    }

$TMPDIR is a standard environment variable on any Unix platform.  I don't see a
good reason that this code isn't just:


sub GetHTMLRunDir {
...
  if (!defined $Dir) {
      $Dir = $ENV{'TMPDIR'};
      if (!defined $Dir) { $Dir = "/tmp"; }

especially since /tmp/ can have limited storage available.
