Bus error when Catch2 tries catching an exception when using Clang 19

[quantheory]

Describe the bug
When Catch2 catches an exception thrown by test code in Clang 19.1 (at least the version I have installed using homebrew on my Mac), it results in a Bus error: 10. This occurs regardless of whether or not the exception is raised inside a REQUIRE macro, so long as the exception is caught by Catch2. (If I set up a try block to catch the exception myself before any Catch2 code sees it, it doesn't seem to cause a problem.)

Expected behavior
Catch2 should catch the exception and produce some kind of reasonable output. If in a REQUIRE_THROWS macro where an appropriate exception is raised, the test should pass.

Reproduction steps
This test file was enough to trigger the problem for me:

#define CATCH_CONFIG_MAIN
#include "catch2/catch_test_macros.hpp"


TEST_CASE( "blah", "blah" ) {

  SECTION( "blah" ) {
    throw(std::runtime_error("Hi"));
  }

}

I typically get output like this:

Randomness seeded to: 638767569
Bus error: 10

Platform information:

• OS: macOS 15
• Compiler+version: Clang 19.1 (from homebrew)
• Catch version: v3.7.1 (compiled from source with same version of Clang)

I should note that I'm not positive whether this is really a Catch2 error, or an issue with the particular Clang installation I have. It would be nice to know if anyone else can reproduce the issue.
