>Description:
[ Reported to the Debian BTS as report #169862.
Please CC 169862@bugs.debian.org on replies.
Log of report can be found at http://bugs.debian.org/169862 ]
rechecked with 3.2 branch 20021220 and 3.3 branch 20021227
Not sure if this is a problem with the CPU, the kernel, the compiler,
or the library. But this seems the most likely candidate. Consider the sample
program below. When compiled as
g++ foo.cc -ftrapv -o foo
and run, the resultant binary immediately aborts.
#include <vector>
using namespace std;
typedef vector<int> foo_t;
int main() {
vector<foo_t> V(10, foo_t());
return 0;
}
