Hi alexis-m2osw, thanks for reporting this SIGBUS crash in mod_ssl, and
especially for attaching the core dump; that's really useful. This type
of error often suggests a problem with memory access. Since it's
happening in ssl_io_filter_coalesce and appears intermittently, it's
possible a specific SSL traffic pattern or a race condition might be
triggering it.
To help us investigate further and get closer to a potential fix, could
you provide any additional details that might help reproduce this? For
example, are there specific types of SSL certificates, cipher suites, or
client behaviors that seem to coincide with the crashes? Additionally,
if you can collect Apache logs with LogLevel debug around the time of a
crash, that could provide more specific clues about the state of
mod_ssl's I/O leading up to the issue. Any information you can provide
to help identify a reliable way to reproduce this SIGBUS would be
greatly appreciated.
