Error description

  • You may receive a SIGBUS error (Signal 10 - Bus error) when you
run the COBOL DB2 API sample programs with no embedded SQL on
Solaris and HP-UX.

When trying to run the COBOL sample programs after building with
no error, you will see an error message like the following:


$ ./d_dbconf
Sample COBOL Program : D_DBCONF.CBL

Execution error : file 'd_dbconf'
error code: 114, pc=0, call=1, seg=0
114     Attempt to access item beyond bounds of memory (Signal
10)


You will see a stack trace similar to the following when using a
debugger:
