I downloaded and built 3.4.3 on AIX 5.2, and this bug does still exist; I tried
the following program (scarfed from 13391) and it crashes every time. Is there
any resolution/fix ? 


bluetrance:13391$ more a2.cpp
void mycall()
{
throw 0;
}
bluetrance:13391$ more a1.cpp

 
extern void mycall();
 
int main()
{
try {
mycall();
} catch (int i) {
return i;
}
return 1;
}
 
 
bluetrance:13391$ g++ -fPIC -DPIC -shared -o liba2.a a2.cpp
bluetrance:13391$ g++ -fPIC -DPIC -o a1 a1.cpp -L. -la2
bluetrance:13391$ a1

If I compile and link the example in my last comment (shown below) with
-pthread, it will always run. If I don't it will always core dump. This is with
g++ 3.4.3 on AIX 5.2. Does anyone know if the same program compiled with g++
3.3.3 will behave the same way on AIX 5.2 ? (i.e. run okay when compiled and
linked with -pthread but abort otherwise ?)

bluetrance:13391$ cat a2.cpp
void mycall()
{
throw 0;
}
bluetrance:13391$ cat a1.cpp

 
extern void mycall();
 
int main()
{
try {
mycall();
} catch (int i) {
return i;
}
return 1;
}
 
 
bluetrance:13391$ g++ -fPIC -DPIC -shared -pthread -o liba2.a a2.cpp
bluetrance:13391$ g++ -fPIC -DPIC -o a1 a1.cpp -pthread -L. -la2
