Changing the section behind the compiler's back is bad.  The compiler 
remembers what section it is in to reduce the amount of assembly section 
switching code it emits.  Thus an asm must not change the section.

Try using pushsection/popsection.  Any ELF based assembler should accept 
that, and that will leave you where you began.  If you only need one 
level, then .section/.previous should work too.  See the GNU AS manual 
for more info.

On IA-64, there is the .xdata directive which eliminates the need to 
switch sections before emitting data.  One of the arguments to this 
directive is the section that the data goes into.  This will only work 
for an IA-64 target though.  See the Intel IA-64 assembly language manual.
