I'm not sure but I don't think so. As I understand it, DWARF on Posix and SEH on Windows are zero-cost exception handling systems.

Only the x64 variant of SEH is "zero-cost". On x86, exception handlers must be installed into a linked list in the function prologue, which takes a few pushes/movs and popped off again in the epilogue.
