segfaults on -pthread -static and LD_ASSUME_KERNE=2.2.5

[Sergei Trofimovich <st@vba.com.by>]

Hi! I am using debian sarge-3.1 (updating)

ii  gcc            3.3.5-3        The GNU C compiler
ii  libgcc1        3.4.3-13sarge1 GCC support library
ii  libstdc++5     3.3.5-13       The GNU Standard C++ Library v3
ii  libc6          2.3.2.ds1-22sa GNU C Library: Shared libraries and Timezone

Sample showng bug(?):
# makefile
TARGET := oo

all: $(TARGET)

$(TARGET) : main.cc
        $(CXX) main.cc -o $@ -pthread -static

run: $(TARGET)
        ./$(TARGET)

//main.cc
#include <iostream>

using namespace std;

int
main (int argc, char * argv[])
{
    cerr << "end\n";
    return 0;
}

#run.sh
#!/bin/sh

export LD_ASSUME_KERNEL=2.2.5
ulimit -c unlimited
make run

And now i'm running ./run.sh:
$ ./run
./oo

Binary, compiled in RHEL4, runs successfully.

Is it bug? Is it libc, libstdc++, gcc or kernel bug?
How to fix this program runned in such environment?

Thanks.
