-Subject: [PATCH] libstdc++: Avoid recursion in __nothrow_wait_cv::wait
- [PR105730]
-
-The commit r12-5877-g9e18a25331fa25 removed the incorrect
-noexcept-specifier from std::condition_variable::wait and gave the new
-symbol version @@GLIBCXX_3.4.30. It also redefined the original symbol
-std::condition_variable::wait(unique_lock<mutex>&)@GLIBCXX_3.4.11 as an
-alias for a new symbol, __gnu_cxx::__nothrow_wait_cv::wait, which still
-has the incorrect noexcept guarantee. That __nothrow_wait_cv::wait is
-just a wrapper around the real condition_variable::wait which adds
-noexcept and so terminates on a __forced_unwind exception.
-
-This doesn't work on uclibc, possibly due to a dynamic linker bug. When
-__nothrow_wait_cv::wait calls the condition_variable::wait function it
-binds to the alias symbol, which means it just calls itself recursively
-until the stack overflows.
-
-This change avoids the possibility of a recursive call by changing the
-__nothrow_wait_cv::wait function so that instead of calling
-condition_variable::wait it re-implements it. This requires accessing
-the private _M_cond member of condition_variable, so we need to use the
-trick of instantiating a template with the member-pointer of the private
-member.
-
-libstdc++-v3/ChangeLog:
-
-	PR libstdc++/105730
-	* src/c++11/compatibility-condvar.cc (__nothrow_wait_cv::wait):
-	Access private data member of base class and call its wait
-	member.
