From: "nagachika (Tomoyuki Chikanaga)" Date: 2022-03-12T07:56:16+00:00 Subject: [ruby-core:107858] [Ruby master Bug#18409] Crash (free(): invalid pointer) if LD_PRELOAD doesn't explicitly include libjemalloc.so.2 Issue #18409 has been updated by nagachika (Tomoyuki Chikanaga). Backport changed from 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: REQUIRED to 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: DONE ruby_3_0 09b27ec6a984ec1b660d5b7b48f2ff4d5a0065bc merged revision(s) 737e4432b978eb4b9f5b10fb6cc6d9c883a5d17a. ---------------------------------------- Bug #18409: Crash (free(): invalid pointer) if LD_PRELOAD doesn't explicitly include libjemalloc.so.2 https://bugs.ruby-lang.org/issues/18409#change-96797 * Author: itay-grudev (Itay Grudev) * Status: Closed * Priority: Normal * ruby -v: ruby 3.0.3p157 (2021-11-24 revision 3fb7d2cadc) [x86_64-linux] * Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: DONE ---------------------------------------- I recently installed Ruby 3.0.2 using rbenv with: ``` RUBY_CONFIGURE_OPTS='--with-jemalloc' rbenv install 3.0.2 ``` After running our app it always crashed with: ``` free(): invalid pointer [1] 51364 IOT instruction (core dumped) bundle exec rails assets:precompile ``` I also tried upgrading to `3.0.3` with no success. After researching the bug a lot and lots of failed attempt to track it down I stumbled upon this report: https://github.com/grpc/grpc/issues/25450 that recommended trying: ``` LD_PRELOAD=$LD_PRELOAD:/lib/x86_64-linux-gnu/libjemalloc.so.2 bundle exec rails assets:precompile ``` That seems to have worked, but that can't be the proper solution in production. Surely it shouldn't be required. -- https://bugs.ruby-lang.org/ Unsubscribe:
