Summary: g++ crashes with ICE in bitmap_first_set_bit, at
bitmap.c:770
Product: gcc
Version: 4.5.1
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
g++ 4.5.1 crashes with an internal compiler error on the following C++ code
(trimmed down from a larger codebase - in this shortened state it is clearly
not expected to work/do anything useful):
#include <complex.h>
template<class T>
class ClassA
{
complex double *data;
public:
void setSize()
{
data[0] = 1.0 + 2.0i;
}
};
template<class TCoeff, class TRHS>
class ClassB
{
ClassA<TCoeff> a1;
ClassA<TRHS> a2;
public:
void setSize()
{
a1.setSize();
a2.setSize();
}
};
class ClassC
{
ClassB<double, complex double> d;
virtual void init();
};
void ClassC::init()
{
d.setSize();
}
$ g++ -c z8.cc
z8.cc: In member function ‘void ClassA<T>::setSize() [with T = __complex__
double]’:
z8.cc:41:1: internal compiler error: in bitmap_first_set_bit, at bitmap.c:770
