c++ - AddressSanitizer 拦截器_via_fun

Question

想要抑制 AddressSanitizer 检测到的以下错误。

==114064==ERROR: AddressSanitizer: stack-use-after-scope on address 0x7ffe60fee2f0 at pc 0x000001e6ef34 bp 0x7ffe60feb6c0 sp 0x7ffe60feb6b8
WRITE of size 8 at 0x7ffe60fee2f0 thread T0
    #0 0x1e6ef33 in std::_Function_base::_Function_base() /opt/gcc-8.2.0/include/c++/8.2.0/bits/std_function.h:252
    #1 0x1e6ef33 in function<Engine::Engine(const Resource&, SourceDataVersion, Engine::CalculationResolution)::<lambda(std::unique_ptr<const model::Car>)> > /opt/gcc-8.2.0/include/c++/8.2.0/bits/std_function.h:668
    ...

我在想设置 ASAN_OPTIONS=suppressions=asan_blacklist.txt，包含 asan_blacklist.txt

interceptor_via_fun:_Function_base

可以解决问题，如 documentation说

interceptor_via_fun:NameOfCFunctionToSuppress

但事实并非如此。看到谷歌搜索“AddressSanitizer Interceptor_via_fun”只返回 151 个结果，我感到非常震惊。 :/

我应该在我的抑制文件中放入什么？

你没试过吗llvm手动的？
并添加以下行以抑制您的外部库

interceptor_via_lib:NameOfTheLibraryToSuppress
