db2 clp dumps core with option -l and statements in the input
file (-f) that are bigger than 128 k.
Stack in the core would look like this:
Program terminated with signal 11, Segmentation fault.
#0 0x00002aaaab2ac19a in clpfp_install_signals(void (*)(int,
siginfo*, void*), void (*)(int, siginfo*, void*)) ()
from /home/xyz/sqllib/lib/libdb2.so.1
(gdb) where
#0 0x00002aaaab2ac19a in clpfp_install_signals(void (*)(int,
siginfo*, void*), void (*)(int, siginfo*, void*)) ()
from /home/xyz/sqllib/lib/libdb2.so.1

#6 0x00002aaaab2ac442 in clp_fp_con(int, int, char**) () from
/home/xyz/sqllib/lib/libdb2.so.1
#7 0x00002aaaab2a8138 in clp_api () from
/home/xyz/sqllib/lib/libdb2.so.1
#8 0x0000000000401f23 in main ()
In many cases you would not see a valid stack as it is
overwritten with the statement text, eg:
Core was generated by `end if;
end if;
end if;
set v_endtab'.
Program terminated with signal 11, Segmentation fault.
#0 0x00000032a8860d67 in gets () from /lib64/libc.so.6
In this case a db2trc will help to identify the issue. |
