Bug description: [PATCH] - unicode byte order difference between SPARC and x86
Description:
------------
zspprintf() incorrectly represents strings/chars as unicode characters on
Solaris (SPARC).
There are byte ordering differences for unicode representations between
x86 and SPARC:
For example, the unicode representation (i've grouped them in sets of
2chars) of '/tmp' on x86 is
'/''\0' 't''\0' 'm''\0'
'p''\0'
and on SPARC it is
'\0''/' '\0''t' '\0''m'
'\0''p'
http://marc.info/?l=php-internals&m=125811990106419&w=2
has some more
details.
the problem seems to be in the smart_str_append2c macro that
zspprintf()/xbuf_format_converter end up using.
The following patch fixes the problem:
