Is it possible to convert floating point exceptions (signals) into C++ exceptions on x86 Linux?
This is for debugging purposes, so nonportability and imperfection is okay (e.g., if it isn't 100% guaranteed that all destructors are called).

Due to the way signals and exceptions work, you can't do it immediately when the signal is thrown - exceptions rely on certain aspects of the stack that aren't true when a signal handler gets called (not sure whether you can safely throw....

Where are exceptions stored ? Stack, Heap. How is memory allocated and deallocated for Exceptions? Now if you have more than one exception which needs to be handled are there objects of all these exceptions created?

They can be nested garbage-collected like everything else.
There cannot be two exceptions being thrown at the same time (on the same thread).
I would assume that memory for exceptions is allocated the same way as for all other objects).

I use exceptions in C++ and I miss that feature.
Is there a tool out there capable of doing it? maybe a compiler option (but I doubt it)

Typically this will be enough:
try { //do stuff } catch piece of code - throwing exceptions....
Of course, you really don't want to catch most exceptions at this level, but you can at least to catch all exceptions at the top level.
