> segfault in mime_hdr_set_accelerators_and_presence_bits
> -------------------------------------------------------
>
> Key: TS-733
> URL: https://issues.apache.org/jira/browse/TS-733
> Project: Traffic Server
> Issue Type: Bug
> Components: MIME
> Affects Versions: 2.0.1
> Environment: X6240 AMD64 Debian Lenny (2.6.26) 64G of Ram.
> Reporter: Ricky Chan
> Labels: MIME, segfault
> Fix For: 2.1.8
>
>
> We are seeing segfault and I have now put back unstripped binaries so I can
> get line numbers are frame traces.
> Below is the trace, although GDB claims it's line 482, I believe it's now
> actually there (a short int comparison won't crash it). My interest is the
> fact that m_wks_idx is 67 which is larger than the MAX amount of slots which
> I believe is 16 (0 - 15) right?
> I got this segfault 6 times this morning, and it appears from the same client
> too.
> I'm thinking of patching the code to make sure m_wks_idx isn't >
> MAX_FIELD_SLOTNUM_MAX for now.
