Summary: [4.6/4.7 Regression] ICE: SIGSEGV (recursion in
value_dependent_expression_p) when variable is used
uninitialised
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: zsojka@seznam.cz
Looks similiar to PR46870, but this code is valid:
------- testcase.C -------
template < int > struct S
{
S () { int i = i; i; };
};
--------------------------
Compiler output:
$ gcc -std=gnu++0x testcase.C
Program received signal SIGSEGV, Segmentation fault.
