The following testcase produces an ICE. I couldn't reduce it any further. Fails
with GCC 4.2.2/4.2.3 under i686-pc-linux-gnu/i686-pc-mingw32.
#include <tr1/array>
#include <tr1/memory>
int main()
{
typedef std::tr1::array<std::tr1::shared_ptr<int>, 1> Array;
Array array;
for (Array::iterator iter(array.begin());;)
{
try
{
(iter++)->reset(new int);
}
catch (...) {}
}
}
g++ -O test.cpp
test.cpp: In function 'int main()':
test.cpp:3: internal compiler error: in coalesce_abnormal_edges, at
