Assembler errors in optimization level 3 (-O3) - gcc (4.1.2)

["Srinivas G." <srinivasg@xxxxxxxxxxxxxxxxxxxxx>]

Dear All,

I have written an application where I used a few ASM statements in it.
The statements are very simple and they look like as shown below.

asm
(
	"next:\n\t"
#ifdef __x86_64__
	"pop %rax\n\t"
	"pop %rcx"		
#else
	"popl %eax\n\t"
	"popl %ecx"		
#endif
);

asm
(
	"xorl %eax, %eax\n\t"
	"cpuid\n\t"
	"cmpl $4, %eax\n\t" 	// check if cpuid supports leaf 4
	"jl .single_core\n\t"	// Single core
	"movl $4, %eax\n\t"	
	"movl $0, %ecx\n\t"	// start with index = 0; Leaf 4 reports
);					// at least one valid cache
level
asm
(
	"cpuid"
	: "=a" (Regeax)
	:
	: "%ebx", "%ecx", "%edx"
);		
asm
(
	"jmp .multi_core\n"
	".single_core:\n\t"
	"xor %eax, %eax\n"
	".multi_core:"
);

I am able to compile the application in optimization level 2 (-O2) where
as when I specify the optimization level (-O3) I end up with the
following errors.

{standard input}: Assembler messages:

I have searched the google and did not find any solution. However, I
have gone through the following link and there is no much luck to me.

http://lists.atrpms.net/pipermail/atrpms-users/2005-July/003451.html

One thing, I can mention here is, I did update the packages through YUM
command only. The system configuration is as follows.

1) DELL 64 Bit - Pentium(R) D CPU 3.00 GHz
2) 1 GB RAM
3) Linux - CENTOS - 5.2 with default kernel version - 2.6.18-92.el5
4) gcc version 4.1.2 20071124

Please suggest me a solution to getridof from the above errors.

Thanks in advance.

Thanks and Regards,
Srinivas G
