libstdc++: Fix -Wmaybe-uninitialized false positive [PR103984]
This fixes a false positive warning seen with LTO:
12/bits/regex_compiler.tcc:443:32: error: '__last_char._M_char' may be used uninitialized [-Werror=maybe-uninitialized]
Given that the std::regex code is not very efficient anyway, the
overhead of initializing this byte should be minimal.
libstdc++-v3/ChangeLog:
PR middle-end/103984
* include/bits/regex_compiler.h (_BracketMatcher::_M_char): Use
default member initializer.
