dbx warning after linux & developerstudio12.6 upgrade

Hi,

We have upgraded our application from Oracle Enterprise Linux OEL 7.7 to OEL 8.5(kernal 5.4.17-2136.305.5.4.el8uek.x86_64). Also we have upgraded our CC compiler from 12.3 to Oracle Dev Studio 12.6 CC compiler (32 bit). Our application is 32 bit. After this version upgradation, we are getting some weird warning message while we use "dbx" tool for debugging. Could any one let us know if we are facing this issue due to some library linkages in OEL8.5. We have used CC with -m32 option while we generated executable

Error message is - dbx: internal warning: SigMgr::enable(32, 0). dup enable

Debug log is attached below

[$HOME/ developerstudio12.6]$ ./lib/dbx/32/dbx -xexec32 a.out
