[Bug 1463875] Re: Crash in libnettle6 on armhf and powerpc archs

[Adam Conrad]

This particular portion of the transition is done in -proposed, which
allows the builds being complained about to build again.  The rest of
the transition is still ongoing, but there's no point keeping this bug
open until it's done.

** Changed in: nettle (Ubuntu)
       Status: Confirmed => Fix Released

Title:
  Crash in libnettle6 on armhf and powerpc archs

Status in nettle package in Ubuntu:
  Fix Released
Status in nettle package in Debian:
  Fix Released

Bug description:
  Currently, in wily, some landing silos are blocked now, due to a
  segfault occurring when attempting to run certain test binaries, which
  depend on the gnutls stack. Most notably so far, I've hit this issue
  in projects which are using QtNetwork or libcurl for network access.
  The issue is a crash in libnettle6, with the following stack trace:

  Program received signal SIGSEGV, Segmentation fault.
  0xb6c20b00 in nettle_yarrow256_update ()
     from /usr/lib/arm-linux-gnueabihf/libnettle.so.6
  (gdb) bt
  #0  0xb6c20b00 in nettle_yarrow256_update ()
     from /usr/lib/arm-linux-gnueabihf/libnettle.so.6
  #1  0xb6bd6406 in ?? () from /usr/lib/arm-linux-gnueabihf/libgnutls-deb0.so.28
  Backtrace stopped: previous frame identical to this frame (corrupt stack?)

  There seems to also be no dbgsym package available yet on
  ddebs.ubuntu.com for this package, so I've not been able to get a more
  complete trace.

  This is happening with nettle 3.1.1-3 in wily-proposed.
