Subj : __pthread_internal_tsd_set SIGSEGV on malloc

I'm stumped... Compiling the following program with c++ test.cpp 
-pthread OR OR g++ test.cpp -pthread, I get an identical binary. It's 
slightly different if I use gcc test.cpp -pthread -lstdc++, but, both 
binaries give a segmentation fault in __pthread_internal_tsd_set () from 
/lib/libpthread.so.0  at the point of the malloc (I see "Hello, World!").

Note, I'm cross-compiling for i586 with OpenEmbedded. All the 
OpenEmbedded packages run fine.

Does anyone know what might be causing this?


#include <stdio.h>
#include <malloc.h>

int main()
{
     char buf[32] = "Hello, World!";
     void* buf2;

     printf("%s\n", buf);

     buf2 = malloc(4);

     if (buf2 != NULL)
         printf("Yay!\n");
     else
         printf("%s\n", "No such luck, mister...");

     return 0;
}
