[bug-pcl] PCL5e with bitmap images causes segmentation fault inGhostPCL

[Brian K. White]

Worked for me.
1.41 on sco unix 5.0.6 built with gcc 2.95.3

It did generate error messages, but it didn't crash and it did create a pdf 
that looks OK to me.

Here is the error messages:

# pcl2pdf job.pcl job.pdf

> Hi,

> to provide you with backtraces from gdb as well as straces and debug

> Symptoms:
>
> On a SuSE-linux based server with CUPS installed there is a backend which 
> tries to convert enqueued PCL jobs to PS for analysis. These jobs are 
> created on Win32 system using HP PCL5e printer drivers.
>
> As long as there is only text or vector-based illustrations and tables in 
> it a job gets converted without any problem. As soon as the document 
> contains at least one bitmap image the call to pcl6 binary for conversion 
> fails on SIGSEGV.
>
> We tested this with several documents. First we've been working with 1.38, 
> then upgraded to a freshly downloaded 1.41, but the pcl6 was still 
> crashing.
>
>
> Today I recompiled the source tree (downloaded freshly again) on a 
> different host using SuSE 9.0. Then I tried to convert the job given as an 
> example to you on that web page. Again pcl6 crashed at the same point.

> The web page includes:
>
> 1) the job used to test on the second host. other job files are available 
> as well, but I think this single file is okay for testing, isn't it?
>
> 2) two logs of gdb session observing the crash with backtrace and memory 
> dumps of the section the device handle is located in.
>
> 3) command line, output and strace used on a debuggable version of pcl6 
> compiled in debug mode as given in docs
>
> 4) finally there are two files with detailed information on used gcc and 
> libraries linked by pcl6
>
>
>
> Well all these files come from the server we initially tried to analyse 
> the crash on.

> I hope, these information can help you to help me out of this situation.
