Summary: Generation of debug symbols leads to internal compiler
error
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++

test case leading to internal compiler error
Enabling the generation of debug symbols leads to an internal compiler error
(segmentation fault). A preprocessed minimal example is attached. The problem
is reproducible in g++ versions 4.7.2, 4.7.3, 4.8.0 and 4.8.1. Version 4.7.1 is
the last version where I did not encounter any problems.
// code
template<typename T, long unsigned int N>
struct array {
T data[N];
};
template<typename T>
struct derived {
typedef long unsigned int size_type;
static const size_type n = 42;
array<int, n> a;
};
// compile
$ g++ -g -Wall -Wextra -save-temps test-case.cpp
test-case.cpp:12:2: internal compiler error: Segmentation fault
};
