Description Denis Komissarov 2003-01-14 11:08:04 UTC
Description of problem:

g++ v. 2.96.87 and 2.96.112 on Alpha failes to compile code where function 
takes large parameters by value. 

Version-Release number of selected component (if applicable):

g++ v. 2.96.87 or 2.96.112 

How reproducible:

Simply try to compile example below: 

---------------------------------------- 
typedef struct { 
   char a[1024*34]; 
} tt; 

void f(tt t) 
{ 
} 

main() 
{ 
   tt t;  
   f(t); 
}

Comment 1 Jakub Jelinek 2003-01-15 09:55:33 UTC
7.1/alpha is no longer supported. Grab some newer compiler, like GCC 3.2.1.

Comment 2 Denis Komissarov 2003-01-17 16:54:32 UTC
Compiler g++ 3.2.1 has the same bug on Alpha.

Comment 3 Richard Henderson 2004-10-03 11:53:44 UTC
Fails through gcc 3.3; fixed in gcc 3.4.
