With proper command line options the trivial test case
variant below works just fine on FreeBSD.
// File: lang-gcc-g++-exception-handling.cpp
// On FreeBSD:
// Works: g++13 -static -Wl,--eh-frame-hdr lang-gcc-g++-exception-handling.cpp
-o lang-gcc-g++-exception-handling && ./lang-gcc-g++-exception-handling
// FAILS: g++13 -staticlang-gcc-g++-exception-handling.cpp
-o lang-gcc-g++-exception-handling && ./lang-gcc-g++-exception-handling
int main(int argc, char *argv[])
{
try {
throw (int)0;
} catch (int i) {
return 0;
}
return 1;
}
Such is also true with -static-libgcc -static-libstdc++ added
to the command lines.
I do not know if -Wl,--eh-frame-hdr should be implicit/automatic
for FreeBSD.
My test context was based on:
# uname -apKU
FreeBSD aarch64-main-pbase 15.0-CURRENT FreeBSD 15.0-CURRENT #5

I'll note that the same is true for:
// File: lang-gcc-g++-exception-handling-with-threads.cpp
// On FreeBSD:
// Works: g++13 -static -Wl,--eh-frame-hdr -pthread
lang-gcc-g++-exception-handling-with-threads.cpp -o

void* kernel(void* par) {
printf("kernel\n");
return NULL;
}
int main(int argc, const char* const* args){
pthread_t thread;
pthread_create(
,
NULL,
kernel,
NULL
);
pthread_join(thread, NULL);
printf("FreeBSD doesn't reach here.\n");
return 0;
}
