I'm not sure about Windows, but on Unix the most common reason for
SIGABRT is due to assert() (which calls abort(), which raises
A failed assert() should print the actual test to stderr, but the GUI
might be discarding that.
As for why drag-and-drop may not work, it's important to extract
archives in binary mode, not text mode or "autodetect" (i.e. don't
perform LF->CRLF conversion).
