Both smbd and nmbd crash right after launch on PPC Linux 2.4 after failing to bind to any socket. Excerpt from log is provided below.

The system identifies as Linux 2.4.20_mvl31-ppc_linkstation. 

The problem is ultimately caused by networking code using AI_ADDRCONFIG flag, which is defined, but causes getaddrinfo() to fail when used.
Previous working version of Samba (3.0.28) didn't have this problem. 

#undefining AI_ADDRCONFIG did help.

int main(int argc, char** argv)

    int ret;
    struct addrinfo hints;
    struct addrinfo *ppres = NULL;
    const char* hostname = "0.0.0.0";

    memset(&hints, '\0', sizeof(hints));
    hints.ai_socktype = SOCK_STREAM;
    hints.ai_family = AF_INET;
    hints.ai_flags = AI_ADDRCONFIG;
    
    ret = getaddrinfo(hostname, NULL, &hints, &ppres);
    if (ret != 0) 
    	fprintf(stderr, "getaddrinfo('%s'), flags=0x%08x failed. return value=%d; errno=%d\n", hostname, hints.ai_flags, ret, errno);

It fails on this system:
getaddrinfo('0.0.0.0'), flags=0x00000020 failed. return value=-1; errno=0
