Compiler aborts on Ubuntu 12.04

[GoogleCodeExporter]

This is on 64bit.

As of version 21dbd579e541 on 2/20 I get this whenever the crack or crackc 
binaries are run:

$> ./crack -l lib test/test_math.crk
terminate called after throwing an instance of 'spug::Exception'
  what():  std::exception
Aborted (core dumped)

The gdb backtrace:

[Thread debugging using libthread_db enabled]

Another data point: dladdr() fails when it tries to load the math functions for 
double precision numbers.

If I print out functions getting registered in Math.cc, I get e.g.
Added function sin64(angle)=0x7faa5f74ec50

and then in LLVMBuilder::createExternFunc:

Looking up function sin64: 0x7faa5f74ec50
Unable to locate symbol for extern function: sin64

A simple demonstration looks like this:

module.cc:

#include <math.h>
#include <stdio.h>

typedef double (OneFuncDouble)(double);
OneFuncDouble *one_funcs_double[]= { sin, cos, tan, NULL };

extern "C" {
    void **module_init(){
        static void* func_array[4];

        for (int i=0; i<4; i++){
            func_array[i] = (void*)one_funcs_double[i];
            if (one_funcs_double[i])
                printf("Registering symbol %p\n", (void*)one_funcs_double[i]);
        }

        return func_array;
    }
}

main.cc:

#include <dlfcn.h>
#include <stdio.h>

typedef void **(init_func)();

void **test_init(){
    static void *retval[] = {NULL};
    return retval;
}

int main(int argc, char **argv){
    void *module = dlopen("module.so", RTLD_NOW);
    init_func *myfunc;
    myfunc = &test_init;

    if (module){
        init_func *module_init = (init_func *)dlsym(module, "module_init");
        void **func_array = module_init();
        Dl_info symInfo;
        for (int i=0; func_array[i]; i++){
            if (dladdr(func_array[i], &symInfo)){
                if (symInfo.dli_sname)
                    printf("Found symbol %s\n", symInfo.dli_fname, symInfo.dli_sname);
                else
                    printf("ERROR: symbol for %p not found\n", func_array[i]);
            }
        }
    }
    else printf("Failed to load module\n");

    return 0;
}

Makefile:

all: module.so test_module

test_module: main.o
    g++ -fPIC $< -o $@ -ldl

module.o: module.cc
    g++ -fPIC -c $< -o $@

module.so: module.o
    g++ -fPIC -shared -Wl,-soname,module.so -o $@ $<
