Description Volker Reichelt 2006-07-18 10:37:42 UTC 
The following invalid code snippet triggers an ICE since GCC 4.1.0
(only with the C frontend):

========================================
void foo() x;

const char* p = __FUNCTION__;
========================================

bug.c: In function 'foo':
bug.c:1: error: expected declaration specifiers before 'x'
bug.c:3: error: parameter 'p' is initialized
bug.c:0: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]
