[Bug c/14911] New: static const symbols lost when referred in asm

[monge at sns dot it]

could not compile MPlayer with 3.4 prerelease :-( 
 
gcc -v : 
 Reading specs from /usr/lib/gcc/i686-pc-linux-gnu/3.4.0/specs 
Configured with: ../configure --prefix=/usr --program-suffix=-3.4 --with-gnu-as 
--with-gnu-ld --with-cpu=i686 --enable-__cxa_atexit --enable-languages=c,c++ 
Thread model: posix 
gcc version 3.4.0 20040407 (prerelease) 
 
the follwing code: 
 
//------------BEGIN--------------- 
static const int hello = 56; 
int main() 
{ 
	asm( 
	"mov hello, %eax\n" 
	); 
	return 0; 
} 
//------------END----------------- 
 
compiles with  
 
gcc code.c 
 
but fails with 
 
gcc -O2 code.c 
/tmp/ccgUsUmb.o(.text+0xd): In function `main': 
: undefined reference to `hello' 
collect2: ld returned 1 exit status 
 
gcc 3.2.3 always works. 
 
Thanx
