egcs1.0.2 in-class function screws switch table

While debugging some code I discovered that my egcs1.0.2 mingw32 compiler
is generating an invalid jump-address table for a switch construct if the
function in question is defined in-class. Ie, this works:
class Child2: public Parent {
int textstuff (int w) ;
};
int Child2::textstuff(int w){
switch(w){
case 0: doSomething(1); break;
case 1: doSomething(2); break;
}
return(1);
}
but this doesn't:
class Child2: public Parent {
int textstuff (int w) {
switch(w){
case 0: doSomething(1); break;
case 1: doSomething(2); break;
}
return(1);
};
};
After much gdb'ing I determined the problem was the compiler-generated
jump table for the switch statement. It's garbage for the case that
doesn't work.
Has anyone seen this before?
