(This is where an exception is raised in a C++ function executed by inferior function call, and no in-frame exception handler results in a sigabrt being delivered to the inferior). As this is a very useful flag, and it only seems to apply in inferior function calls, I am curious why it appears to default as "off", requiring the user to perform: set unwindonsignal on (I'm not advocating changing it, just curious if there is a particular reason for it to be this way). And also, if there would be known side-effects to having it to default as on. Regards Phil
