            Bug ID: 110210
           Summary: problem with strtol strtoll strtoul strtoull
           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 strtol, strtoll, strtoul, and strtoull functions in code to convert
values that exceed the representation range,

Incorrect error number after execution

The requirement of C standard for this Class function: if the correct value
exceeds the representation range, LONG_ MIN, LONG_ MAX, LLONG_ MIN, LLONG_ MAX,
ULONG_ MAX or ULLONG_ MAX (corresponding symbol bit) will be used as the return
value, and the value of macro ERANGE will be stored in errno.

During testing, it was found that the returned errno was not an ERANGE value

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Gcc does not provide these functions. They are provided by the libc that gcc
links to.

In the case of Linux, it is most likely glibc but it could be musl or uclibc .

If you are using a -elf target, then libc is most likely provided by newlib.


Also GCC 4.8.x is no longer supported upstream, you should try a much newer
GCC, like GCC 9.x or even better GCC 13.
