SIGSEGV when compiled with boost 1.88 and link-time optimization

[bartlibert]

When the library is built with boost 1.88 and link-time optimization, I get an immediate segfault in any program linked with cpprestsdk.

I have patched the library to be able to compile with boost 1.88.
I use the following patches:
boost-1.88.patch
warnings.patch
fix-clang-dll-import.patch

Minimal test case program

#include <iostream>
int main (int argc, char *argv[]) {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

Compile and link with cpprestsdk:
g++ test.cpp -lcpprest -lcrypto

Running the resulting binary results in an immediate segmentation fault. Backtrace:

When disabling link-time optimization during compilation of cpprestsdk, the segfault is gone and everything works as expected.
