--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Erroneous expressions include negative ones, as in PR 105077:
#include <new>
#include <stdexcept>
int main()
{
try
{
int negative = -1;
new char[negative];
}
catch(const std::bad_array_new_length &e)
{
}
return 0;
}
This throws bad_alloc instead of bad_array_new_length.
PR 99934 is another example where we should not call the allocation function,
but the FE should return a nullptr instead of throwing.
