I really don't know what I could be doing wrong, but on a _stock_ FC4
install, I'm having a segfault in a pthread call, specifically when
statically linked and including iostream (or other STL includes like string)
Here's the code:
#include <pthread.h>
#include <iostream>
int main(int argc, char *argv[])
{
pthread_mutexattr_t attr;
pthread_mutexattr_init( &attr );
}
And I compile with:
g++ -g -c example.c
g++ -static -g -o example example.o -lpthread
The resulting program crashes in pthread_mutexattr_init. If I merely
remove the include of <iostream>, it works fine. This also works fine
on FC3.
A dynamic linking variation that blows up:
g++ -g -o example example.o (leave off the -lpthread, yes this links)
I also noticed that there are _2_ libpthread.so files. One in /usr/lib,
and another in /lib which is the one ldd points to.
Finally, if I remove the <iostream> include, and attempt to dynamically
link, it _finally_ complains about not finding the
pthread_mutexattr_init call. Was it somehow getting a
pthread_mutexattr_init from the libstdc++ library??
Can anyone else confirm this crash? Has anyone else seen this problem?
I've googled everywhere, and even posted to 2 forums without *any*
response. And, yes, I must statically link in my case.
Thanks for any help,
Lee
