Line 72:

			x[k] = x[k]*10 + c-'0';

I don't understand why this read access to x[k] is initialized.
If I change the declaration of local array x[] as:

  uint32_t x[KMAX] = { 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1};

then:

$ ./a.out
1.123
...
y = 11.123

Initializing x[] with arbitrary values shouldn't change anything
if it was not used uninitialized, right?

Even if I am getting something wrong here, you can count on me
to test the heck out of your function. I initially subscribed to
the musl mailing because I had been looking for a function like
this (although I let the musl source code distract me then).
