Motivation

When an OOM exception (std::bad_alloc) is thrown, the C++ runtime unwinds the stack before termination, destroying the backtrace. Until now, catching the backtrace required attaching cuda-gdb and reproducing the run from scratch — which is expensive, especially when OOM occurs late in a long run (e.g. 1B-vector ANN indexing).

What this PR does

Introduces an LD_PRELOAD intercept on __cxa_throw() that captures the full backtrace before stack unwinding begins, for both host and device exceptions.

Usage:
LD_PRELOAD=intercept_throw.so ./program
(program should be built with debug symbols)

On OOM, the full symbolized backtrace is printed to stderr automatically, without debugger and re-run needed.

Example output

=== intercepted throw, backtrace ===
