Re: newlib functions at address 0x0

Hi Noé,

  This is probably a linker problem or possibly a compiler problem, so 
it would be better if you sent this bug report to the binutils mailing 
list (for the linker) at: binutils@sources.redhat.com or else the gcc 
mailing list (for the compiler) at: gcc-bugs@gcc.gnu.org.

What command line are you using to:

  a) compile your sine function ?
  b) link your compiled sine function into an executable ?

Are you using a customised linker script ?  If so then this could be the 
cause of your problems.

Which version of the compiler and linker are involved ?

Are you able to create a *small* self-contained test case which 
reproduces this problem ?  If so that would greatly help somebody track 
down and fix the bug.
