I have the same problem on PHP 5.3.2 on 32-bit Linux.

Configure:

'./configure' '--with-apxs2=/usr/local/apache2/bin/apxs' '--with-
mssql=/usr/local/freetds' '--with-ldap' '--prefix=/usr/local/php5'
'--with-
config-file-path=/usr/local/php5/etc' '--enable-sockets' '--enable-soap'
'--
with-openssl' '--with-unixODBC=/usr' '--with-gd'
'--with-jpeg-dir=/usr/lib' '--
with-pdo-odbc=unixODBC,/usr' '--with-pdo-dblib=/usr/local/freetds'


uname -a:

Linux servername 2.6.16.60-0.42.5-default #1 Mon Aug 24 09:41:41 UTC
2009 i686

Appears to hang when compiled for 32bit Intel code, but not 64bit code.

Hangs in zend_strtod() according to gdb.

Happens here too 64bit CPU 32bit builds (win or linux)

How about -O2 -ffloat-store ?

looking like a gcc optimizer bug, -O0 is fine where -O2 hangs
