Description Jeffrey Graham 2003-03-11 11:59:00 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3b) Gecko/20030210

Description of problem:
The following code segfaults when compiled statically.

#include <pthread.h>
#include <iostream>

pthread_mutex_t                 outMutex;

static float i(0);

void*   test_1(void* arg)
        std::cerr<<"Hello "<<i++<<std::endl;
        return static_cast<void *>(NULL);

int     main()

        pthread_t       workThreadID1;

        if ( 0 != pthread_create(&workThreadID1, NULL, test_1, NULL) )
                std::cerr<<"Error creating workthread1"<<std::endl;

        if ( 0 != pthread_join(workThreadID1,NULL) )
                std::cerr<<"pthread_join() failed for workthread1"<<std::endl;

        return 0;

My makefile:
CXXFLAGS+= -pthread

test: test.C
        $(CXX) $(CXXFLAGS) -o $@ $^ $(LDFLAGS) -lpthread

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.compile the above
2.run it
3.it will seg fault
4. comment out the Makefile line that adds -static
5. compile it
6. it runs ok.


Actual Results:  exactly as described.

Expected Results:  should behave the same whether it is linked dynamically or

Additional info:

using a custom 2.4.20 kernel. gcc 3.2 20020903 (RHLinux 8.0 3.2-7)

Changing the float to an int works!

This works for me just fine, at least on a RHL9 system.  Please update and try
