Purpose of APR_PROGRAM and APR_PROGRAM_ENV is reversed in apr_proc_create

           Summary: Purpose of APR_PROGRAM and APR_PROGRAM_ENV is reversed
                    in apr_proc_create
           Product: APR
           Version: 0.9.4
          Platform: PC
        OS/Version: Solaris
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: APR
        AssignedTo: bugs@httpd.apache.org
        ReportedBy: mcorcoran@spidersoftware.com


It looks as though the purpose that APR_PROGRAM and APR_PROGRAM_ENV are 
supposed to serve in apr_proc_create() in (apr/threadproc/unix/proc.c) is being 
implemented the wrong way.

The problem being that when a call is made to apr_proc_create() with NULL for 
the env argument, and APR_PROGRAM is specified in the attr argument, then NULL 
ends up getting passed to the call to execve, which seems to cause the exec'ed 
program to seg fault before it even has a chance to run.  This was most 
noticeable to me while trying to use rotatelogs and SSLPassPhraseDialog 
exec:/blah/blah.

Here's a simple diff to fix it:
diff ./httpd-2.0.48/srclib/apr/threadproc/unix/proc.c ./httpd-
2.0.48.fix/srclib/apr/threadproc/unix/proc.c
482c482
<             execve(progname, (char * const *)args, (char * const *)env);
---
>             execv(progname, (char * const *)args);
489c489
<             execv(progname, (char * const *)args);
---
>             execve(progname, (char * const *)args, (char * const *)env);

Thanks.
