Internal compiler error at dwarf2out.c:1341

[Denis Komissarov]

Hi!

I found a bug in Alpha version of g++.

Description of problem:

g++ v. 2.96.87 and 2.96.112 and 3.2.1 on Alpha failes to compile code where 
function 
takes large parameters by value. 

How reproducible:

Simply try to compile example below: 

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

void f(tt t) 
{ 
} 

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

Actual results:

Compiler 2.96.112 reports:

gcc-test.c: In function `int main ()':
gcc-test.c:13: Internal compiler error in dwarf2out_frame_debug_expr, 
at dwarf2out.c:1341
