Bug #20496
closed![Assignee: yjit](/images/group.png?1722288379)
Segfault when enabling YJIT
Description
I installed Ruby 3.4-dev via rbenv to see how the improvements in YJIT with 3.4-dev (after reading https://speakerdeck.com/k0kubun/rubykaigi-2024) translate to other parts of HexaPDF. However, when running the HexaPDF optimization benchmark with YJIT enabled, it regularly segfaults. This does not happen without YJIT.
Steps to reproduce¶
- Clone the HexaPDF repository:
git clone git@github.com:gettalong/hexapdf.git
- Download the file
a.pdf
attached to this issue into thehexapdf
directory. - Change into the
hexapdf
directory and runruby --yjit -I lib bin/hexapdf -f optimize --compress-pages a.pdf out.pdf
. - The run may not fail every time but it does fail with a segfault many times.
Segfault output¶
/tmp/hexapdf/lib/hexapdf/task/optimize.rb:289: [BUG] Segmentation fault at 0x00000000000000b0
