Ok, I've tested one of the CVS-snaps, and it worked. So I think it's
"closed" now and not "bogus".
M:\php\php5-win32-200306301130>echo "<? var_dump(array(M_PI,pi())); ?>"
| php -q
"array(2) {
[0]=>
float(3.1415926535898)
[1]=>
float(3.1415926535898)
}

Tested on Win2k SP3, fails exactly as described by reporter:
C:\PHP\5.0.0b1>echo "<? var_dump(array(M_PI,pi())); ?>" | php -q
"array(2) {
[0]=>
float(3)
[1]=>
float(3)
}
"
Definitely not bogus.

Tested on Windows and Linux, works on both.

Description:
------------
Yeah right. PI = 3 ... given a big enough 3 and a small enough pi ...
Reproduce code:
---------------
<? var_dump(array(M_PI,pi())); ?>
Expected result:
----------------
M:\php>echo "<? var_dump(array(M_PI,pi())); ?>" | 431\php -q
"array(2) {
[0]=>
float(3.1415926535898)
[1]=>
float(3.1415926535898)
}
"
Actual result:
--------------
M:\php>echo "<? var_dump(array(M_PI,pi())); ?>" | 500b1\php -q
"array(2) {
[0]=>
float(3)
[1]=>
float(3)
}
"
