Bug 18468 – cannot use `synchronized {}` in @safe code

@safe void main() { synchronized {} } onlineapp.d(4): Error: safe function 'main' cannot access __gshared data '__critsec15' onlineapp.d(4): Error: safe function 'main' cannot access __gshared data '__critsec15' onlineapp.d(4): Error: variable onlineapp.main.__critsec15 __gshared not allowed in safe functions; use shared this is due to the compiler rewriting synchronized { foo();} // line 15 as __gshared ubyte[critsec.sizeof + size_t.sizeof] __critsec15; _d_criticalenter(__critsec15.ptr); try { foo(); } finally { _d_criticalexit(__critsec15.ptr); } instead of __gshared ubyte[critsec.sizeof + size_t.sizeof] __critsec15; _d_criticalenter(&__critsec15[0]); try { foo(); } finally { _d_criticalexit(&__critsec15[0]); }

Im an idiot and can't read, still this should work.

Yep, looks like this is really trivial to fix: https://github.com/dlang/dmd/pull/7918
