Testcase
Using clang r252597 win64. Using the attached test program:
λ clang-cl checksec.cpp
λ
Works fine, now lets see /EHsc:
λ clang-cl /EHsc checksec.cpp
checksec-649d19.obj : error LNK2019: unresolved external symbol "void __cdecl
terminate(void)" (?terminate@@YAXXZ) referenced in function "int `public:
__cdecl MappedImage::~MappedImage(void)'::`1'::dtor$10"
(?dtor$10@?0???1MappedImage@@QEAA@XZ@4HA)
checksec.exe : fatal error LNK1120: 1 unresolved externals
clang-cl.exe: error: linker command failed with exit code 1120 (use -v to see
invocation)
Ok then use /EHsc- :
λ clang-cl /EHsc- checksec.cpp
checksec-280639.obj : error LNK2019: unresolved external symbol "void __cdecl
terminate(void)" (?terminate@@YAXXZ) referenced in function "int `public:
__cdecl MappedImage::~MappedImage(void)'::`1'::dtor$10"
(?dtor$10@?0???1MappedImage@@QEAA@XZ@4HA)
checksec.exe : fatal error LNK1120: 1 unresolved externals
clang-cl.exe: error: linker command failed with exit code 1120 (use -v to see
invocation)</pre>
