sentry-native: Immediate segfault on Linux (Manjaro)

Description

The sentry SDK segfaults immediately when using the getting started code. I have a screenshot of the backtrace: image It appears to segfault somewhere in curl, which is being called from curl_easy_perform in sentry_transport_curl.c

  • During build
  • During run-time
  • When capturing a hard crash

Environment

  • OS: Manjaro (arch derivative)
  • Compiler: GNU 10.1.0
  • CMake config: -DCMAKE_BUILD_TYPE=Debug
  • CURL: 7.70.0

Steps To Reproduce

Place this snippet in main.

sentry_options_t *options = sentry_options_new();
    sentry_options_set_debug(options, true);
    sentry_options_set_dsn(options, "<dsn>");
    sentry_init(options);
    sentry_capture_event(sentry_value_new_message_event(
            /*   level */ SENTRY_LEVEL_INFO,
            /*  logger */ "custom",
            /* message */ "It works!"
    ));

@Shamazo Thank you for posting your issue here! Just starting hitting this exact crash after upgrading our machines to Ubuntu 22.04 (which has openssl 3). It took me a bit to find it, since the stack was different – we got a segfault with a stack that looks like this:

    #0 0x7fe9113194d8 in OPENSSL_sk_value (/lib/x86_64-linux-gnu/libcrypto.so.3+0x2064d8)
    #1 0x7fe91133ba19 in X509_STORE_add_lookup (/lib/x86_64-linux-gnu/libcrypto.so.3+0x228a19)
    #2 0x7fe911341f5e in X509_STORE_load_file_ex (/lib/x86_64-linux-gnu/libcrypto.so.3+0x22ef5e)

After trying a bunch of different things without success (and finding that using libcurl w/ gnutls fixed it), I stumbled across your issue, and realized that we’re statically linking OpenSSL 1.1 into our application as well as loading sentry-native built with dynamic OpenSSL 3. Removing the statically linked OpenSSL 1.1 from the build resolved the issue.
