Segfault with ZnClient and https

Hi, I have trouble with latest Fedora 33, plain installation and Pharo 8.0
stable, 64 bit.

When I try a

ZnClient new url: 'https://something..'; get.

The image segfaults.

Last lines from log are:

primitiveSSL:setStringProperty:toValue:
atAllPut:
atAllPut:
primitiveSSL:connect:startingAt:count:into:

stack page bytes 8192 available headroom 5576 minimum unused headroom 5952

It seems libssl and libcrypto is bundled togheter with Pharo, looks like
version 1.0.0.

I then try to compile openssl with 1.0.0-stable which I build myself, but
when replacing the Pharo-libs with my own I get the message that I am using
a too old tls-version error.

I am a little confused on what is happening here. Do anyone have a clue?

(git checkouts over ssh works fine, strange enough)

Petter

Hi Petter,

It should work, but of course there might be something wrong.
To get a baseline for your issue here is what I did, and what you could try to repeat.

You could try to use ldd to try to figure out if you have any missing libraries.

Actually, this is nicer, simpler and clearer:

$ ./pharo Pharo.image eval "ZnClient new get: 'https://pharo.org/web/files/pharo.png'; response"
a ZnResponse(200 OK image/png 34696B)

Hi Sven and thanks for answering!

I did try a ldd and all libraries are present. I also started pharo with gdb
and it seems problem is somewhere in the combination between libgit2.so,
libssl.so and libcrypto.so.1.0.0, most often the crash comes from libssl.so.

Exchanging libgit2.so with the os-version make ZnClient work, but then
Iceberg on the other hand stops working.

I pretty much gave up Fedora and reverted to safe Ubuntu. Maybe I can dig
deeper into this later, but we are pretty close to a production setting now
:)
