The unwinder delegates the decision of whether to stop in a call frame to - that call frame's language-specific personality function. Not all personality - functions guarantee that they will stop to perform cleanups. For example, the - GNU C++ personality function doesn't do so unless the exception is actually - caught somewhere further up the stack. When using this personality to - implement EH for a language that guarantees that cleanups will always be run - (e.g. Ada), be sure to indicate a catch-all in the - landingpad instruction - rather than just cleanups.
