I have not reproduced the error here, but I will change it to openssl by default. If you want to use libressl, please refer to the comment out in the PKGBUILD and make the necessary changes. With the conditions you have presented, I don't think the built-in mruby is enabled, so the conditions will not be the same, but please give it a try.

I downloaded the most recent version of H2O from Git using the master branch, which according to the website is the official version:

As of April 2023, we have ceased to release versions. Rather, each commit to the master branch is considered stable and ready for general use except for the features marked as experimental.

I used below PKGBUILD, which builds clean. The resulting binary does not crash constantly as before.

build() {
        cd "$srcdir"/h2o
        cmake -DCMAKE_INSTALL_PREFIX=/usr .
        make
}

package() {
        cd "$srcdir"/h2o

        make DESTDIR="$pkgdir" install
}

Is it just me or are there others who experience constant breakdowns of h2o? I get below error every 105 minutes of execution:

Or is this New HTTP/2 DoS attack can crash web servers with a single connection?

Version in question:

$ h2o -v
h2o version 2.3.0-DEV@16ea5ef09
OpenSSL: LibreSSL 3.9.1
mruby: YES

libaegis: YES

Info on CFLAGS in /etc/makepkg.conf:

CFLAGS="-march=native -mtune=generic -O2 -pipe -fno-plt -fexceptions \

        -fstack-clash-protection -fcf-protection"

A peek into the core dump gives:

@The_Decryptor

This was not a decision not to use libressl, but to expand the choice of multiple TLS implementations to choose from.

The_Decryptor commented on 2023-10-29 08:51 (UTC)

Is the libressl dependency still needed? Upstream switched away from it a few years ago as it was only used due to OpenSSL lacking features at the time.

I'm using an h2o build without mruby for a long time. I've just built with mruby enabled and found it hard to build. After patching parse.y, there's still another build problem.
