Bug ID: 27492
Summary: llvm-symbolizer on windows report function name
incorrectly
Product: new-bugs
Version: unspecified
Hardware: PC
OS: Windows XP
Status: NEW
Severity: normal
Priority: P
Component: new bugs
Assignee: unassignedb...@nondot.org
Reporter: vitalyb...@google.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
Reproducer is below. I use bash on Windows, so make sure to update paths if
needed.
>From build directory:
1. cmake -G Ninja ../llvm/
2. ninja -j 10 clang asan llvm-symbolizer
3. bin/clang.exe -fsanitize=address -mno-omit-leaf-frame-pointer
-fno-omit-frame-pointer -fno-optimize-sibling-calls -gline-tables-only
-gcodeview -fms-compatibility-version=19.00.23918 -std=c++11 -O1 -mllvm
-asan-use-after-scope=1
../llvm/projects/compiler-rt/test/asan/TestCases/use-after-scope-capture.cc -o
use-after-scope-capture.cc.exe
4. ./use-after-scope-capture.cc.exe
You should see crash with:
#0 0x1231f83 in main()::(anonymous class)::operator()
d:\src\clang.git\llvm\projects\compiler-rt\test\asan\TestCases
\use-after-scope-capture.cc:11
#1 0x1231f1e in std::_Invoker_functor::_Call C:\Program Files

cc:10:9',std::allocator<int>,int>::_Do_call C:\Program Files (x86)\Microsoft
Visual Studio 14.0\VC\INCLUDE\functional:21
Symbolizer was not used yet.
5. cp bin/llvm-symbolizer.exe .
6. ./use-after-scope-capture.cc.exe
Actual result:
Now llvm-symbolizer.exe is visible for asan runtime and it outputs:
#0 0x221f83 in main
d:\src\clang.git\llvm\projects\compiler-rt\test\asan\TestCases\use-after-scope-capture.cc:11:14
#1 0x221f1e in main C:\Program Files (x86)\Microsoft Visual Studio
14.0\VC\INCLUDE\type_traits:1398:11
#2 0x221eee in main C:\Program Files (x86)\Microsoft Visual Studio
14.0\VC\INCLUDE\type_traits:1466:10
#3 0x221ece in main C:\Program Files (x86)\Microsoft Visual Studio
14.0\VC\INCLUDE\type_traits:1491:10
#4 0x2218ae in main C:\Program Files (x86)\Microsoft Visual Studio
14.0\VC\INCLUDE\functional:212:11
Expected correct result:
Stack with more detailed function names, e.g. #0 0x1231f83 in
main()::(anonymous class)::operator()
Another reproducer:
4. ASAN_OPTIONS=symbolize=0 ./use-after-scope-capture.cc.exe
5. see something like: #0 0x3d1f83
(d:\src\clang.git\build\use-after-scope-capture.cc.exe+0x401f83)
6. copy address after + (here 0x401f83)
7. run bin/llvm-symbolizer.exe
8. type:
CODE
use-after-scope-capture.cc.exe 0x401f83
Result:
CODE
main
d:\src\clang.git\llvm\projects\compiler-rt\test\asan\TestCases\use-after-scope-capture.cc:11:14
Expected:
CODE
main()::(anonymous class)::operator()
d:\src\clang.git\llvm\projects\compiler-rt\test\asan\TestCases\use-after-scope-capture.cc:11:14
