Hi Jakub,

the new testcase FAILs on Solaris:
+FAIL: g++.dg/torture/pr89303.C -O0 (test for excess errors)
+FAIL: g++.dg/torture/pr89303.C -O1 (test for excess errors)
+FAIL: g++.dg/torture/pr89303.C -O2 (test for excess errors)
+FAIL: g++.dg/torture/pr89303.C -O2 -flto (test for excess errors)
+FAIL: g++.dg/torture/pr89303.C -O2 -flto -flto-partition=none (test for
excess errors)
+FAIL: g++.dg/torture/pr89303.C -O3 -fomit-frame-pointer -funroll-loops
-fpeel-loops -ftracer -finline-functions (test for excess errors)
+FAIL: g++.dg/torture/pr89303.C -O3 -g (test for excess errors)
+FAIL: g++.dg/torture/pr89303.C -Os (test for excess errors)
Excess errors:
ld: warning: symbol 'typeinfo for std::bad_weak_ptr' has differing sizes:
(file /var/tmp//ccB1o8Ya.o value=0x8; file
/var/gcc/regression/trunk/11-gcc/build/i386-pc-solaris2.11/./libstdc++-v3/src/.libs/libstdc++.so
value=0xc);
/var/tmp//ccB1o8Ya.o definition taken
I suspect the class can just be renamed in pr89303.C to avoid the
conflict with include/bits/shared_ptr_base.h?
