Description:
------------
Build php on solaris with Sun compiler:

The default build for 64 bits, i.e. CFLAGS='-m64' produces strange results.
Rebuilding all with CFLAGS='-m64 -O -xs -xstrconst -zlazyload' seems to work.

To reproduce it:

$obj[0]['data'][0]['Usr'] = 0.009035;
echo json_encode($obj);

with just CFLAGS='-m64'
[{"data":[{"Usr":INF}]}]

with CFLAGS='-m64 -O -xs -xstrconst -zlazyload'
[{"data":[{"Usr":0.009035}]}]
which is correct.

may be a problem in main/snprintf.c and in main/spprintf.c

regards 




Test script:
---------------
$obj[0]['data'][0]['Usr'] = 0.009035;
echo json_encode($obj);


Expected result:
----------------
[{"data":[{"Usr":0.009035}]}]

Actual result:
--------------
[{"data":[{"Usr":INF}]}]

Same here.
PHP 5.3.6.

# cc -V
cc: Sun C 5.10 SunOS_i386 2009/06/03

Same workaround does help (thanks, Michael, by the way).

I am not able to reproduce this behavior on both sparc as well as x86 platforms 
? I am using Oracle Solaris Studio 12.2 (formerly Sun Studio compiler)

[sn123202@zod]'php-5.3.6'>cc -V
cc: Sun C 5.10 SunOS_sparc Patch 141861-07 2010/12/09
usage: cc [ options] files.  Use 'cc -flags' for details


Possible, you are running into a compiler bug to me. In any case, you are using 
a really older version of compiler. So, you might wanna consider upgrading or 
installing latest compiler patches.

So, if some thing fixes by using -m64 -O but reproduces with -m64 -  is most 
likely a compiler issue. this is, -m64 doesn't do much but rather than expands 
the compiler flags to build on 64-bit platform. 


I would like to close this bug as not a valid bug
