#163 Error unrecognizable insn

[Giles]

MinGW 4.7.1 fails to compile this code:

#include <stdio.h>
static FILE *volatile fd;
void f(void) { fd = stdout; }

Producing the following error:

D:\Sources\src\DE\Test.cpp: In function 'void f()':
D:\Sources\\src\DE\Test.cpp:3:52: error: unrecognizable insn:
(insn 8 7 9 3 (set (mem/v/f/c:SI (symbol_ref:SI ("_ZL2fd") [flags 0x2] <var_decl 050d88a0 fd>) [0 fd+0 S4 A32])

Sorry. I put it in the wrong place. I copied it in Bug section but can't remove it from here.

We do not distribute GCC 4.7.1. You should try GCC 4.7.2 to see if your issue is resolved. If it is not open a bug report with GCC. See http://gcc.gnu.org/bugs
