Hi Martin,
  I removed the meta-yocto layer, which removed poky distro from the config. And I am still seeing same issue.

[nitin at nbuild0 /]$ cd /usr/local/oecore-x86_64/
[nitin at nbuild0 oecore-x86_64]$ ls
environment-setup-x86_64-oe-linux  site-config-x86_64-oe-linux  sysroots  version-x86_64-oe-linux
[nitin at nbuild0 oecore-x86_64]$ . environment-setup-x86_64-oe-linux
 [nitin at nbuild0 oecore-x86_64]$ sysroots/x86_64-oesdk-linux/usr/bin/x86_64-oe-linux/x86_64-oe-linux-gdb
*** glibc detected *** sysroots/x86_64-oesdk-linux/usr/bin/x86_64-oe-linux/x86_64-oe-linux-gdb: double free or corruption (out): 0x00007f3221852030 ***
