Today I got stuck with a weird behaviour with my c++ project. There is the code which doesn't catch exception from standard library (the same snippet works well on intel mac and under linux machines).
Code snippet:
#include <exception>
#include <stdexcept>
#include <iostream>
#include <string>
int main() {
try {
std::stod("notanumber");
} catch (const std::invalid_argument&) {
std::cerr << "Caught std::invalid_argument" << std::endl;
}
}
Compilation command:
clang++ -fno-rtti main.cpp -o main && ./main
Clang versions:
clang++ --version
Homebrew clang version 15.0.3
Target: arm64-apple-darwin21.6.0
Thread model: posix
InstalledDir: /opt/homebrew/opt/llvm/bin
Also tried:
Apple clang version 14.0.0 (clang-1400.0.29.102)
Target: arm64-apple-darwin21.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
Output:
libc++abi: terminating with uncaught exception of type std::invalid_argument: stod: no conversion
[1] 65643 abort ./main
Expected output:
Caught std::invalid_argument
