I experience on Windows 7 (not on XP) some problems that may be related. I would like to test your workaround, but sigproc.cc has much changed since then, there is now an exit_thead function with the comment "Exit the current thread very carefully.". I tried to insert Sleep(1000) at the end of exit_thread, immediately before "ExitThread (0)", but this yielded no change at all. Could someone be kind enough to update the workaround for modern sigproc.cc? Very briefly, my problem is that when i "tar xf —use-compress-program=xz", i get: tar: Unexpected EOF in archive tar: Unexpected EOF in archive tar: Error is not recoverable: exiting now and the last file of the archive is truncated at some 512bytes block. This occurs on Windows 7 (not on XP); with xz-5.1.3alpha (not with xz-5.1.2alpha or xz-5.0.5); never on most tar.xz files; almost always on some (rare) tar.xz files (one notable example is bc-1.06.95.tar.bz2 bunzip2’ed and then xz’ed); depends on the .tar file itself, not on the option (like -9e, -0) used to create the .tar.xz; never with "tar tf"; and with all tar’s i have tested. The return code of all the involved xz -d commands is always zero though. Perhaps after all, this is unrelated? Thank you.
