<p dir="auto" style="color: #333238; margin: 0 0 16px;" align="initial">Hi,</p>
<p dir="auto" style="color: #333238; margin: 0 0 16px;" align="initial">I've got a core dump which seems to suggest that there's a segfault happening in <code style='font-size: 0.875rem; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: 4px; margin-top: 0; font-weight: inherit; font-family: var(--default-mono-font, "GitLab Mono"),"JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>scm_gnutls_session_record_port</code>. I'm not sure it gives any more information than that, as I don't think Guix builds guile-gnutls with debug info, and I can't seem to work out how to do that.</p>
<p dir="auto" style="color: #333238; margin: 0 0 16px;" align="initial">Maybe this could be another problem that only arises when the garbage collector runs at a very specific time? Similar to that in guile-squee [1], maybe the problem here is that callers of <code style='font-size: 0.875rem; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: 4px; margin-top: 0; font-weight: inherit; font-family: var(--default-mono-font, "GitLab Mono"),"JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>scm_gnutls_session_record_port</code> (e.g. Guile in (web client)) need to ensure that session isn't GC'd prior to <code style='font-size: 0.875rem; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: 4px; font-weight: inherit; font-family: var(--default-mono-font, "GitLab Mono"),"JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>session-record-port</code> finishing?</p>
