--- Comment #1 from Sandra Loosemore <sandra at codesourcery dot com> ---
Hmmm, this looks like a bug in LRA exposed by the change to register alloc
order. In particular this comment in the code just above the assertion seems
to reflect an incorrect assumption:
/* We did not assign hard regs to reload pseudos after two
iteration. It means something is wrong with asm insn
constraints. Report it. */
since there is no inline asm in the test case.

Preprocessed newlib strtod.c source to reproduce issue
This is the newlib example to reproduce this.

--- Comment #3 from Joel Sherrill <joel at gcc dot gnu.org> ---
For the preprocessed newlib strtod source, -O2 will reproduce. Dropping -EL or
to -O1 results in it compiling.
