Question Can't make 09_ConstructorError release already-allocated memory

I've been fiddling with the 09_ConstructorError example, changing the line

Code:
Matrix m(10, 10);
to use different widths and heights. What I've found is that I can't seem to make it act as it's supposed to, i.e. to allocate memory until allocation finally fails, and then delete[] all the previously-allocated 1-dimensional arrays and then exits with a bad_alloc exception. Instead, if I use small to moderate values for the matrix bounds, it just allocates successfully and exits normally; but if I set really high bounds, it exits with a SIGKILL, apparently without releasing any of the already-allocated arrays (I can tell because I've put some debug statements in the deallocation part).

I've tried this on Mac OS X and Linux, but not Windows. What am I doing wrong?
