Don't use floats very often myself so this is just speculation.

What happens is you try:
  sprintf(foo, "%f is a float", 8675.309);

sprintf %f is expecting a double and I don't know if the compiler
will promote an explicitly set float to a double when passed as a
parameter.

Next I'd be looking at the storage that foo is pointing at.  Is it
somewhere that might be overwritten or reused ?
