• On Red Hat Enterprise Linux 7, the hypot output returns "inf", while the same execution returns "nan" on the latest RHEL release as on Red Hat Enterprise Linux 8.9 and Red Hat Enterprise Linux 9.3.

Please provide the package NVR for which bug is seen:

libm,GCC from RHEL 7

How reproducible: Always

Steps to reproduce:

Save the attached code in a c file as "test.c".

Compile this code and create out file with below command:

# gcc -lm test.c
{{}}
Now execute the out file and check the results:
{{}}
on RHEL8: The result is same on first gcc package shipped with RHEL8 till latest:

1. ./a.out
   a = nan
   hypot = nan <<---------

on RHEL7: The result is same on first gcc package shipped with RHEL7 till latest:

1. ./a.out
   a = nan
   hypot = inf <<---------

   Expected results: the hypot output returns "nan"

   Actual results: the hypot output returns "inf"
