A compound statement in GCC’s C parser was not resetting the musttail attribute after encountering a statement with that attribute. This oversight led to spurious errors later in the compilation process. This commit fixes the issue by ensuring that the musttail state is always reset at the end of a compound statement, preventing incorrect error reporting.
