v2.4.2-rc-3-gd7d373d

Version 2.4.2, release candidate

• Fix: fixed crash in assert failure reporting when there was no diff.
  If the user-provided function to stringify an object was bugged and
  produced equal output for non-equal objects, thus producing an empty
  diff, Criterion crashed trying to access an unset parameter list.
• Fix: fixed crashing tests when Criterion was compiled with nanopb>=0.4.7
  (Balazs Scheidler).
• Fix: fixed deadlock when test timeout was specified and the system was
  overloaded.
• Fix: fixed segfault if map_shdr fails (David Gloe).
• Fix: fixed memory leak on test failure (Jookia).
• Fix: fixed gt() and ge().
• Fix: escape XML/JSON reports.
• Misc: converted klib and debugbreak submodules to subprojects
  (Cristian Prieto).
• Misc: various documentation fixes (Yuri Victorovich, Jonas Schulze).
• Misc: various updates to dependencies.
