[poppler] Segmentation fault happens with poppler_page_render in pdftotext

[andy huang]

Hi All:
  I want to transfer one pdf page to text file and png file at the same
function.
So I use the pdftotext.cc to implement my function , but I always encounter
the segmentation fault problem.
The text part and poppler_page_render part is running ok individually.
But when I put text part and render part together , the program always dead
at poppler_page_render function.
I hope someone can help me to figure out this situation.

I attach the source code and binary file
Here is the log file
--------------------------------------------------------------
./pdftotext -f 1 -l 1 -raw /home/andy/pdf/English.pdf eng1.txt
start to load pdf file
png pdf 3
png pdf 4
png pdf 5
***** MediaBox = ll:0,0 ur:612,792
***** CropBox = ll:0,0 ur:612,792
***** Rotate = 0
Segmentation fault
------------------------------------------------------



Thank you very much.
Best regards
Andy
