同样遇到了这个问题，用ImageMagick/utilities/.libs/magick 文件。 或者编译时加上--disable-shared选项，但是即使在编译时加上了-g选项，这种方式还是会导致没有符号。

确实，如果用gcc编译时看log是有符号信息的。 用clang+ASAN编译时就没有符号信息（具体体现在遇到了ASAN的报错，只会显示magic+0xXX出了问题，但是不会显示对应的源码是第几行）因此就无法定位到是源码中的第几行出了问题了。 排查了一下clang编译后的binary，使用file命令查看magick二进制文件是没有strip的，gdb加载该binary后，运行poc后，如果使用CTRL+C暂时中断程序，是可以看到对应的符号的，只是ASAN的log中没有符号。  请问这可能是什么原因导致的呢？ @lcatro 环境： - ubuntu18.04 / ubuntu16.04均测试过 - clang 3.8.0和3.9.0均测试过 举例： gcc: ``` ==2775==AddressSanitizer CHECK failed: ../../../../src/libsanitizer/sanitizer_common/sanitizer_common.cc:118 "((0 && "unable to mmap")) != (0)" (0x0, 0x0)...

解决了。@lcatro clang开启ASan编译选项时，calltrace中的符号信息是依赖llvm的llvm-symbolizer来做的。因此确保llvm-symbolizer在环境变量中即可。 详细可以参考这里：https://github.com/google/sanitizers/issues/1043

客气了，向前辈学习。

I have the same problem. When use `proxychains4 curl www.google.com`, it works well. However, when use `proxychains4 nmap -Pn -sT 61.135.169.121` , all ports are open. Is there anyone fix...
