*zsh* handles the "out of memory" scenario gracefully now The *zsh* shell allocates memory while printing the `out of memory` fatal error message. Previously, if the printing routine failed to allocate memory, it triggered an infinite recursion. Consequently, the *zsh* process terminated unexpectedly due to a stack overflow. With this update, the infinite recursion no longer appears in this scenario. As a result, after printing the fatal error message, *zsh* now terminates gracefully in case it runs out of memory.
+++ This bug was initially created as a clone of Bug #1300958 +++ --- Additional comment from Kamil Dudka on 2016-01-25 14:56 CET --- Created attachment #1118021 [details] proof-of-concept reproducer I have attached a universal reproducer script. It is not completely reliable because dynamic linker and pthread run-time may run out of memory sooner than zsh itself in some cases. Nevertheless, I am able to trigger the infinite recursion with upstream git HEAD if I create a statically linked executable. --- Additional comment from Kamil Dudka on 2016-01-25 16:22:58 CET --- reported upstream: http://www.zsh.org/mla/workers/2016/msg00310.html --- Additional comment from Kamil Dudka on 2016-01-27 09:25:40 CET --- upstream commits: https://sourceforge.net/p/zsh/code/ci/be32864e https://sourceforge.net/p/zsh/code/ci/69c86cd2 --- Additional comment from Kamil Dudka on 2016-01-27 10:08:07 CET --- fixed in zsh-5.2-4.fc24
