[squid-users] Squid crashes with 3.5.1

[Prashanth Prabhu]

Hi Amos,

I patched in the bug fix -- I assume the patch file listed in the bug
report is the most current? -- but it didn't help. I saw the same
crash in a couple of patched systems. The stack trace is pasted below.

As I pointed out in my earlier email, the crash occurs with c-icap
connections, whereas the fix appears to have been targeted at SSL
connections. Sounds to me like this must be a different issue
altogether. Are there any other fixes that may resolve this issue?

Thanks.
Prashanth

Stack trace.
