The problem is that perl exit()s rather than die()s which make recovery on failure a bit problematic.

Reducing the memory footprint of the application is a work around but in the case of PDL where the perl SV data is actually an opaque object being processed by optimized C computational kernels, it is not "relatively simple" to implement

I'm thinking that a possible approach would be to replace the implicit perl memory allocation with our own calls to the system malloc routine with the perl object reference now being controlled by magic or some such...

I'm fine with a failure to allocate these large objects but would like the perl interpreter not to exit. The current pdl_malloc using perl SVs is definitely far outside the bounds of expected perl usages. However, one of the goals of PDL was to make exactly such memory and computational performance problems accessible from perl.
