#26769 [Opn->WFx]: 64 bit pointer

ID: 26769 Updated by: pollita@php.net Reported By: yu at fstrf dot org -Status: Open +Status: Wont fix Bug Type: Compile Warning Operating System: Solaris 8/sparcv9 PHP Version: 4.3.4 New Comment: It's a harmless warning. rsrc->ptr is a generic use "bucket". Generally it's meant to hold a pointer to some data. In this case, pid_t is trusted to never have a larger storage size than void* (to do so would require 16-bit pointers and 32-bit PIDs or 32-bit pointers and 64-bit PIDs, etc...) so rather than malloc()ing a container for child, we just drop child itself into the pointer bucket. Bottom line, don't worry. Previous Comments: ------------------------------------------------------------------------ [2004-01-02 17:12:02] yu at fstrf dot org Description: ------------ I am compiling PHP under solaris 8 /sparcv9 for 64-bit version. I get a successful compilation except the following warnings. php-4.3.4/ext/standard/exec.c:588: warning: cast from pinter to integer of different size php-4.3.4/ext/standard/exec.c: In function `zif_proc_open': php-4.3.4/ext/standard/exec.c:1007: warning: cast to pointer from integer of different size Here is the code in exec.c, ----------------------------------------------------------- line# 586: pid_t child, wait_pid; line# 587: line# 588: child = (pid_t)rsrc->ptr; . . . line# 1007: ZEND_REGISTER_RESOURCE(return_value, (void*)child, le_proc_open); ----------------------------------------------------------- Since pid_t is defined in solaris8/sparv9 in 32 bit and pointer is 64 bit, I am worried an assignment from 64-bit pointer to a 32-bit integer would cause segmentation fault in the runtime. Can anybody help me on that? Thank you, Maggie ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26769&edit=1
