Summary: zend_parse_parameters(): Incorrect parsing of the
first parameter
Status: Bogus
Type: Bug
Package: Unknown/Other Function
Operating System: fedora core 16 x64
PHP Version: 5.3.9

x64 int is 4 bytes, long is 8 bytes. In the example zend_parse_parameters is
being told to write 8 bytes into a 4 byte variable, and the address where the
high 4 bytes would be if they existed happens to be (although this is platform
specific and undefined) the address of the int string length. It's completely
to be expected.
If you're telling zend_parse_parameters you're giving it a long (as in "sls")
then actually give it one. I.e., "long p_long;".

@cataphract,
Sorry, don't get you: from what do you deduce that that is a "platform specific
undefined behavior"? This behaviour you can easily stumble upon after 5.3.6 if
develop module.

As felipe as said "l" is for "long". This bug tracker is not the place to
explain platform specific undefined behavior.

Incorrect parsing first parameter when type_spec = "sls" (e.g.)
zend_parse_parameter() return string length as 0, always. See example #1 and #2:
PHP Warning: First parameter: 'first' and it len: 0 in Command line code on
line 1

@felipe, do you read what subject says?
Please elaborate on "'l' expects a 'long', not an 'int'" of yours and on how
does it relate to the problem.
This ticket is about string length param is set to 0 upon specified
circumstances.
