icx with enabled address sanitizer under Windows and C++ throw crash

[Frank_R_1]

Hi,

Consider the following reproducer:

//////////////////////////////////////////////////////////////////////

// icx.exe -O3 -Ob2 -Zi -EHsc -MD -fsanitize=address test.cxx

// ASAN_OPTIONS=alloc_dealloc_mismatch=0,detect_leaks=0,halt_on_error=0,detect_stack_use_after_return=true,check_initialization_order=true,check_malloc_usable_size=0,detect_odr_violation=1,handle_segv=1
#include <cstdio>
#include <exception>

int main(){
try {
throw std::exception("test");
}catch (const std::exception& ex){
puts(ex.what());
}
return 0;
}

Program will terminate with:

>./test.exe

Consider also:

https://github.com/google/sanitizers/issues/749

So address sanitizer is not useable under Windows in C++ programs with throw instructions.

Is there a workaround?

Best regards

Do you meant that if you compiled like this: icx -O3 -Ob2 -Zi -EHsc -fsanitize=address test.cxx
You'd get the error you mentioned?

If I compiled like what you said icx -O3 -Ob2 -Zi -EHsc -MD -fsanitize=address test.cxx (with that -MD)
I actually got another error saying "the procedure entry point ??3@YAXPEAX@Z could not be located in the dynamic link library", which is the same problem you asked a few days ago: https://community.intel.com/t5/Intel-oneAPI-DPC-C-Compiler/Windows-debug-build-with-icx-and-address-sanitizer-crash-with/m-p/1592947#M3683

Hi,

You need to copy

clang_rt.asan_dynamic-x86_64.dll

into  your folder where the executable is located!

Then type

set ASAN_OPTIONS=alloc_dealloc_mismatch=0,detect_leaks=0,halt_on_error=0,detect_stack_use_after_return=true,check_initialization_order=true,check_malloc_usable_size=0,detect_odr_violation=1,handle_segv=1

in your cmd.exe

and run

.\test.exe

Hi,

Just as an information:

On Linux everything works!

We have a lot of unit/integration/regression-tests which ran on Linux but fail on Windows due to exception handling problem of sanitizer : (

Best regards

I've escalated your issue to our internal engineering team. We'll come back with the update when we reach the conclusion.

Hi,

This compilation error has been resolved and the fix can be expected in the upcoming compiler release.

Hi,

Unfortunately in Intel oneAPI 2024.2 with Windows 10/VS 2019 the reproducer below does not work!

#############################################################

//icx -Od -EHsc -Z7 ex.cxx
//works with output "Caught error no. 5 exception at ex.cxx in line 15"

//icx -Od -fsanitize=address -EHsc -Z7 ex.cxx
//crashes with "Caught error no. Segmentation fault"
#include<iostream>
struct Error {
int a;
};
void info(const char* f, const int l, const Error& e) {
std::cout << "Caught error no. " << e.a << " exception at " << f << " in line " << l << std::endl;
}
int main() {
try {
throw Error{5};
} catch (Error &e) {
info(__FILE__, __LINE__, e);
return 0;
}
return 1;
}

#############################################################

Everything on Linux now works very nice and stable, the exact same code base on Windows crashes in the exceptions catch. (Have a look in the debugger)

ASAN_OPTIONS are:
alloc_dealloc_mismatch=0,detect_leaks=0,halt_on_error=0,detect_stack_use_after_return=true,check_initialization_order=true,strict_string_checks=true,check_malloc_usable_size=true,detect_odr_violation=1,strict_init_order=1,use_odr_indicator=1,handle_segv=0
