This problem still exists in 3.3 20021008 and 3.2.1 20021009 on
i686-pc-linux-gnu. As mentioned earlier, it's a regression from
GCC 2.95.3.
The PR name ought to be "c++" rather than "middle-end".
At the time of the ICE in find_function_data, 'exp' in expand_expr is
a SAVE_EXPR whose function context, 'context', is cloned from
'current_function_decl'. The code in expand_expr falsely assumes that
since 'context' is different from 'current_function_decl', 'context' is
a containing function. It calls find_function_data just to make sure
that 'context' is for a containing function, but it's not so that
function aborts.
I don't where to go from here, but hope that this information will be
of use to someone familiar with the C++ front end.

Hi,
the bug can be reproduced with the following code snippet
(just compile with g++ -c):
----------------------------snip here------------------------
class A
{
A( int );
};
A::A ( int i )
{
int ar[1][i];
ar[0][0] = 0;
}
----------------------------snip here------------------------
The bug is a regression from gcc 2.95.3 (it first appears in gcc 3.0
and is still present in the main trunk - checked on mips-sgi-irix6.5).
Greetings,
Volker Reichelt
