* [Bug c++/39038] New: Redeclaration @ 2009-01-30 4:35 mahesh dot balasubramanian at wipro dot com 2009-01-30 7:21 ` [Bug c++/39038] Redeclaration rguenth at gcc dot gnu dot org ` (3 more replies) 0 siblings, 4 replies; 5+ messages in thread From: mahesh dot balasubramanian at wipro dot com @ 2009-01-30 4:35 UTC (permalink / raw) To: gcc-bugs Hello, I found a strange behavior of the following code. void fn(int x, int y){ if(int temp = ( x > y ? (x /y) : (x % y))){ cout << temp; } else{ double temp = x / y; // ill-formed, redeclaration of temp cout << temp; } } int main(int argc, char **argv){ fn(2, 3); } According to $6.4/3 (14882_1998), This code is ill-formed. But g++ does not through any error or warning. But comeau and vc++ are throwing errors. $6.4/3 A name introduced by a declaration in a condition (either introduced by the type-specifier-seq or the declarator of the condition) is in scope from its point of declaration until the end of the substatements controlled by the condition. If the name is re-declared in the outermost block of a substatement controlled by the condition, the declaration that re-declares the name is ill-formed. Thanks and Regards, Mahesh.
