[bug] Crash in String Matcher

Describe the bug

The following

        try {
            std::string a{ "string" };
            std::string const expected{ "string" };
            REQUIRE_THAT(a, Matches(expected));
        }
        catch (std::exception const& e) {
            std::cerr << std::format("caught '{}'\n", e.what());
        }

works as expected. If I get a bigger expected string (e.g. ~110kByte) it crashes with

...
[ctest] due to a fatal error condition:
[ctest]   SIGSEGV - Segmentation violation signal

The problem is related to the Matches matcher - the following doesn't crash:

        // Catch2's matchers haven't support for string_view
        std::string const expected_str{ csv_data::CsvSV };

        try {
            std::string a{ "string" };
            REQUIRE_THAT(expected_str, Matches(a));
        }
        catch (std::exception const& e) {
            std::cerr << std::format("caught '{}'\n", e.what());
        }

Expected behavior I must not crash in that way, even I've a try/catch block/scope!

Reproduction steps

See above.

Platform information:

OS: Windows NT with devcontainer in VS Code running Ubuntu24.04
Compiler+version: gcc version 13.2.0 (Ubuntu 13.2.0-23ubuntu4)
Catch version: 3.4.0-1build1 amd64

Additional context

How can I ignore line endings with matchers? My reference data contains 16 rows with 161 columns in lines.
```
constexpr std::string_view const CsvSV =
R"(0,0.999994607194946,...
...
...,0.783392372240895
)";
```
How can a make a diff of the strings compared? E.g. only give the line number of difference?
