Package: g++-4.4
Version: 4.4.2-5
Severity: normal
The bug may be rather in libc6-dev, which defines:
htons to __bswap16 if optimize && little endian,
and __bswap16 in bits/byteswap.h
# define __bswap_16(x) \
(__extension__ \
({ register unsigned short int __v, __x = (x); \
if (__builtin_constant_p (__x)) \
__v = __bswap_constant_16 (__x); \
else \
__asm__ ("rorw $8, %w0" \
: "=r" (__v) \
: "0" (__x) \
: "cc"); \
__v; }))
I'm not expert enough with gcc inline assembly to guess what the exact
problem is, but it is definitely in this macro or the way gcc handles it,
but since gcc <= 4.2 noes not show any warning in optimize it, I'd rather
think it is a gcc (4.3 & 4.4) regression
