#25665 [NEW]: var_dump/print_r hang on NaN and INF

From: eru@php.net Operating system: Linux RH 9 PHP version: 4CVS-2003-09-25 (stable) PHP Bug Type: Variables related Bug description: var_dump/print_r hang on NaN and INF Description: ------------ Summary and reproducing code say all... I tested it on a 4.3.0 and got NAN -INF float(0.E+79) float(-0.E+79) which isn't correct on the var_dump behaviour either, but at least I hadn't had a hanging program. Reproduce code: --------------- <?php print_r(acos(1.01)); print_r(log(0)); var_dump(acos(1.01)); var_dump(log(0)); ?> Expected result: ---------------- Some output saying NaN and INF. Actual result: -------------- Nothing. -- Edit bug report at http://bugs.php.net/?id=25665&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=25665&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=25665&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=25665&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=25665&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=25665&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=25665&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=25665&r=support Expected behavior: http://bugs.php.net/fix.php?id=25665&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=25665&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=25665&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=25665&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=25665&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=25665&r=dst IIS Stability: http://bugs.php.net/fix.php?id=25665&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=25665&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=25665&r=float
