Re: [boost] coroutine library?

When pth switched user context it did not switch exception handlers. For
example
Coroutine A:
try{
switch_to_B();
throw 1;
}
catch(int){
printf("catched in A")
}

 Coroutine B:
try{
switch_to_A();
printf("bbb");
}
catch(int){
printf("catched in B")
}

main:
create_A(); create_B(); switch_toA();

result: catched in B

It was on gcc 3.4.4 under cygwin and linux_at_nslu2
