            Bug ID: 110209
           Summary: problem with strtod strtof strtold
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: irip at qq dot com
  Target Milestone: ---

When using strtod, strtof, and strtold functions in code to convert values that
exceed the representation range,

The error number after execution is incorrect, and the error message is:

Got 37 Expected 38 Errno return.


Requirements for this Class function in Standard C: if the correct value
exceeds the range of representation, it is necessary to add/subtract the value
(corresponding to the sign bit) HUGE_ VAL, HUGE_ VALF or HUGE_ After VALL,
return and save the value of macro ERANGE in errno.

During testing, it was found that the errno returned was not the ERANGE value,
and the ERANGE value in the error message was not a common 34, but 38
