I am running into a problem with a package that I have developed using g++ 4.3.2 20081105, even though the problem exists in 4.1.x as well. The package compiles and runs correctly if I compile the code for production. That is, compiling without the coverage and profiling options. Here's the compiler output at link time. /bin/sh ../libtool --tag=CXX --mode=link g++ -g -O3 -funroll-loops -Wall -I/usr/local/include -I/usr/local/include/lwes-0 -I/usr/local/include/json -L/usr/local/lib -o netlog-listen netlog-listen.o libnetlog.la -lresolv -lnsl -lfl -L/usr/local/lib -L/usr/local/lib -llwes -ljson g++ -g -O3 -funroll-loops -Wall -I/usr/local/include -I/usr/local/include/lwes-0 -I/usr/local/include/json -o .libs/netlog-listen netlog-listen.o -L/usr/local/lib ./.libs/libnetlog.so /usr/local/lib/liblwes.so -lresolv -lnsl -lfl /usr/local/lib/libjson.so -Wl,--rpath -Wl,/usr/local/lib But when I configure the code with coverage and profiling options, the compiler chokes at link time: /bin/sh ../libtool --tag=CXX --mode=link g++ -g -funroll-loops -Wall -I/usr/local/include -I/usr/local/include/lwes-0 -I/usr/local/include/json -fprofile-arcs -ftest-coverage -L/usr/local/lib -o netlog-listen netlog-listen.o libnetlog.la -lresolv -lnsl -lfl -L/usr/local/lib -L/usr/local/lib -llwes -ljson g++ -g -funroll-loops -Wall -I/usr/local/include -I/usr/local/include/lwes-0 -I/usr/local/include/json -fprofile-arcs -ftest-coverage -fstack-protector -shared -L/usr/local/lib -o netlog-listen netlog-listen.o libnetlog.la -lresolv -lnsl -lfl -L/usr/local/lib -L/usr/local/lib -llwes -ljson /usr/bin/ld: .libs/netlog-listen: hidden symbol `__stack_chk_fail_local' in /usr/lib/libc_nonshared.a(stack_chk_fail_local.oS) is referenced by DSO /usr/bin/ld: final link failed: Nonrepresentable section on output collect2: ld returned 1 exit status make[1]: *** [netlog-listen] Error 1 Adding -shared to CFLAGS allows me to link as was suggested in some user groups. However, the produced binaries crash as soon as I run them. Running it under gdb is to no avail; it doesn't produce any meaningful stack trace. I'm sure someone must have seen this and that I'm doing something stupid here. Would appreciate it if someone could let me know what is wrong here.
