my program does not single step with gdb in kdevelop

My program run like this:
$ snmpbulkwalkap -v 2c -c public

I compile with "-g" option:
/bin/sh ../libtool --mode=compile gcc -I../include -I../include -I.. -I./.. -I./../snmplib -I./../agent -I../agent/helpers -I./../agent/mibgroup -g -O2 -Dlinux -c -o snmpbulkwalkap.lo snmpbulkwalkap.c
rm -f .libs/snmpbulkwalkap.lo
gcc -I../include -I../include -I.. -I./.. -I./../snmplib -I./../agent -I../agent/helpers -I./../agent/mibgroup -g -O2 -Dlinux -c snmpbulkwalkap.c -fPIC -DPIC -o .libs/snmpbulkwalkap.lo
gcc -I../include -I../include -I.. -I./.. -I./../snmplib -I./../agent -I../agent/helpers -I./../agent/mibgroup -g -O2 -Dlinux -c snmpbulkwalkap.c -o snmpbulkwalkap.o >/dev/null 2>&1
mv -f .libs/snmpbulkwalkap.lo snmpbulkwalkap.lo
/bin/sh ../libtool --mode=link gcc -o snmpbulkwalkap snmpbulkwalkap.lo -L../snmplib -L../agent -L../agent/helpers ../snmplib/ -lcrypto -lm
gcc -o .libs/snmpbulkwalkap snmpbulkwalkap.o -L/home/tcma/net-snmp-5.1.1/snmplib -L/home/tcma/net-snmp-5.1.1/agent -L/home/tcma/net-snmp-5.1.1/agent/helpers ../snmplib/.libs/ -lcrypto -lm -Wl,--rpath -Wl,/usr/local/lib
creating snmpbulkwalkap

Inside kdevelop, I set two breakpoints at lines:
fprintf(stderr, "tcma 1 argc %d\n", argc);
fprintf(stderr, "tcma 2\n");

When the debugger is started inside kdevelop, it stopped at the first breakpoint, when I click the "Step over" button, the debugger do not single step to next line.

This is the gdb output:
