I find that the argc and argv values that are passed to a shared library constructor for a library that is compiled using clang fails. I get the same result using FreeBSD 11.0-RELEASE, 11.1-RELEASE and 12-CURRENT When compiling the attached code using $clang -c -fPIC attrconst.c=20 $clang -shared -o libattrconst.so attrconst.o $clang -L . main.c -lattrconst -o test and executing (bash)=20 $LD_LIBRARY_PATH=3D. ./test I get: Initializing library.=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 Got 3 params. argv[0] is (null). Running the test. Finalizing library. Which is not what I was expecting. Compiling the library using gcc, gives the correct result: $gcc -c -fPIC attrconst.c=20 $gcc -shared -o libattrconst.so attrconst.o $gcc -L . main.c -lattrconst -o test $LD_LIBRARY_PATH=3D. ./test Initializing library.=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 Got 1 params. argv[0] is ./test. Running the test. Finalizing library. Could this be a bug in clang? --=20 You are receiving this mail because: You are the assignee for the bug.=
