Formatting the WebSphere error log, using
ex 'bbo.sbboexec(bborlog)' 'bbo.log noformat'
causes a storage overlay and produced the following error
messages.

CEE3703I In HPCB Control Block, the Eye Catcher is damaged.
CEE3704I Expected data at 8CEBFA1C : HPCB.

CEE0802C Heap storage control information was damaged.
         From entry point operator delete?(void*) at compile
         unit offset +000000E2 at address 1A59D66A.

The reported storage overlay resulted because log browser module
bborblog.cpp incorrectly calculated the message length.
Problem conclusion
Log browser module bborblog.cpp was modified to use the length
returned from bborslog.plx when reading the message from the
stream thus eliminating the reported storage overlay.
