patch 9.0.1835: Perl interface has problems with load PL_current_context Commit: https://github.com/vim/vim/commit/7a9d1aa878d8724e28893b968016b86a3a70c63f Author: Yee Cheng Chin <ychin.git@gmail.com> Date: Fri Sep 1 18:46:17 2023 +0200 patch 9.0.1835: Perl interface has problems with load PL_current_context Problem: Perl interface has problems with load PL_current_context Solution: Fix Perl interface to load PL_current_context from library In #12914, in order to fix an issue with Perl 5.36 dynamic builds, (that version introduced a thread-local `PL_current_context`), the file added the variable manually so we can satisfy the linker. However, the variable is a different one from the one in the library, so there could be unpredictable behavior. Instead, just use `dlsym` to load the context from the library. The fact that it's thread-local doesn't matter too much to us because Vim's interface is single-threaded so it will work properly. closes: #12996 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Yee Cheng Chin <ychin.git@gmail.com>
