Hi Dilip and Vignesh,

I checked the Cfbot and noticed that one of the 'CompilerWarnings' [1]
flow is failing with:
describe.c: In function 'describeSubscriptions':
describe.c:7456:29: error: 'logdest' may be used uninitialized
[-Werror=3Dmaybe-uninitialized]
7456 | if (strcmp(logdest, "table") =3D=3D 0 || strcmp(logdest, "all") =3D=
=3D 0)
| ^~~~~~~~~~~~~~~~~~~~~~~~
describe.c:7356:29: note: 'logdest' was declared here
7356 | char *logdest;
| ^~~~~~~
cc1: all warnings being treated as errors
