Hi. The following program leads to a core dump.

#!/usr/sbin/perl -w

undef($/);

%functions = ();

foreach $file (@ARGV) {
(open(FILE, $file)) || (die "Can't open $file for reading: $!; stopped");

my($input) = <FILE>;

$^D = 14 + 512;

while ($input =~ m/^([_a-zA-Z]+[^\n\(]*)
(\(.*\)(?!\s*\;)[^\{]*\{.*?\}(?=.*?(?:^[_a-zA-Z]+)|\Z))/mgx) {
$^D = 0;
my($what) = $1;
my($found) = $1 . $2;
my($output) = $file . ":\n\t" . $found;
if (exists($functions{$what})) {
$functions{$what} .= "\n" . $output;
} else {
$functions{$what} = $output;
}
}
$^D = 0;

close(FILE);
}

print join("\n\n", map {$functions{$_}} (sort (keys %functions))) . "\n";

The stack trace is as follows:

    This is a bug report for perl from easmith@beatrice.rutgers.edu,
    generated with the help of perlbug 1.26 running under perl 5.00502.

    -----------------------------------------------------------------
    [Please enter your report here]

    Hi. The following program leads to a core dump.

    #!/usr/sbin/perl -w

    undef($/);

    %functions = ();

    foreach $file (@ARGV) {
    (open(FILE, $file)) || (die "Can't open $file for reading: $!; stopped");

    my($input) = ;

    $^D = 14 + 512;

    while ($input =~ m/^([_a-zA-Z]+[^\n\(]*)
    (\(.*\)(?!\s*\;)[^\{]*\{.*?\}(?=.*?(?:^[_a-zA-Z]+)|\Z))/mgx) {
    $^D = 0;
    my($what) = $1;
    my($found) = $1 . $2;
    my($output) = $file . ":\n\t" . $found;
    if (exists($functions{$what})) {
    $functions{$what} .= "\n" . $output;
    } else {
    $functions{$what} = $output;
    }
    }
    $^D = 0;

    close(FILE);
    }

    print join("\n\n", map {$functions{$_}} (sort (keys %functions))) . "\n";

    The stack trace is as follows:

    Core from signal SIGSEGV: Segmentation violation

    :This is a bug report for perl from easmith@beatrice.rutgers.edu,
    :generated with the help of perlbug 1.26 running under perl 5.00502.

    The latest stable version of perl is 5.005_03 - please try your
    program under that version.

    :Hi. The following program leads to a core dump.
    :
    :#!/usr/sbin/perl -w
    :
    :undef($/);
    :
    :%functions = ();
    :
    :foreach $file (@ARGV) {
    : (open(FILE, $file)) || (die "Can't open $file for reading: $!; stopped");
    [snip]

    I was unable to reproduce your problem with a 5.005_02 perl here,
    when I tried throwing some random C source files at it. However I
    have no idea what the program is trying to do or what style of data
    it expects, and there was no output from the program when I tried
    running it.

    If your problem persists under 5.005_03, please a) reduce the test
    case so that both code and data are as small as possible and b)
    provide the necessary data as well as the code in your bug report.

    Thanks,

    Hugo van der Sanden

    Sage advice. However, the keys "complex regex", "data-dependent", and
    "core dump" index the phrase "stack overflow due to deep recursion in regex
    engine" for me. While your stack trace doesn't suggest that recursion's
    your problem, you might try running the script against your data with an
    increased stack allocation to see if the problem goes away. Whatever the
    outcome, please let us know.
