Pthread dynamic linking problem

Hi.

We're using use ELDK 3.0 with kernel linuxppc_2_4_devel from DENX CVS on =
a Lite5200 board.
The problem arises linking a program with a library using fopen and the =
pthread lib dynamically. My program gets stucked when doing a fopen =
call. This doesn't happen if the linking is static (against .a).
Here are an example library and program that show this problem:

* The main program is:

//
// cositas.cpp
//
#include <stdio.h>
#include <pthread.h>

void Polopos(char *fname);

int main(int argc, char **argv)
{
  pthread_t th;
=09
	// Do things
	Polopos("/etc/AVMRecorder.conf");

  return 0;
}

* The library it uses along with pthread lib is:

//=20
// acasitos.cpp
//
#include <stdio.h>

void Polopos(char *foo)
{
	fprintf(stderr, "Opening file %s...\n", foo);
	FILE* cositas =3D fopen(foo, "rt");
	fprintf(stderr, "...file %s open\n", foo);
	fprintf(stderr, "Closing file %s...\n", foo);
	fclose(cositas);
	fprintf(stderr, "...file %s closed\n", foo);
}

* To build the shared lib I issue the following commands:

 @ /usr/local/ppc_82xx/bin/ppc_82xx-g++ -c -o acasitos.o =
-I/usr/local/ppc_82xx/local/include acasitos.cpp
 @ /usr/local/ppc_82xx/bin/ppc_82xx-ld -o libacasitos.so acasitos.o

* And for the final binary:

 @ /usr/local/ppc_82xx/bin/ppc_82xx-g++ -o cositas -L. =
-I/usr/local/ppc_82xx/local/include -lpthread -lacasitos cositas.cpp


* The output for the program is:

 Opening file /etc/AVMRecorder.conf...

* The output of strace is:

It remains in the last line until I Ctrl-C the program.

Thanks in advance
