            Bug ID: 28499
           Summary: Couldn't export variable to sub process
           Product: glibc
           Version: 2.32
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: libc

Hi Team,

I am migrating from glibc-2.31 to glibc-2.32 and couldn't export variable's=
 to
child process

Please look into below logs and example code

----
# cat export.sh=20
#!/bin/sh

A=3D5
export A
echo $A
./test.sh
----

----
# cat test.sh=20
#!/bin/sh

echo $A
----

Output with glibc-2.31:

# ldd --version
ldd (GNU libc) 2.31

Output with glibc-2.32:

# ldd --version
ldd (GNU libc) 2.32

# ./export.sh=20

#=20

You could see in glibc-2.31 exported variable is printing in the test.sh fi=
le
but in case of glibc-2.32 it is not.

Note: all other packages with the rootfs is same, except glibc

Tried using busybox and bash (latest version), but no improvement.

Is there a particular commit which causes this issue, I couldn't found any
release notes related to this.

Thanks in advance.

Regards,
Vignesh
