Re: [Swftools-common] Segmentation fault while converting pdf to swf

[Юрий Богданов]

This pdf has 116 pages. 26 of them throw segmentation fault.

Memory usage during converting is realy small (10-20mb).

GDB says on each bad page (some last lines):

VERBOSE paintTransparencyGroup blend=normal softmaskon=1

NOTICE  File contains transparency groups

VERBOSE clearSoftMask statepos=3

VERBOSE Casting gfxline of 0 segments to a stroke-polygon

VERBOSE Casting gfxline of 5 segments (5 line segments) to a gfxpoly

VERBOSE Comparing polygon renderings of size 78x107 and 78x107

VERBOSE Bad SVP rewinding result- polygons don't match

VERBOSE Error in polygon processing

Program received signal SIGSEGV, Segmentation fault.

0x0810cff1 in polyops_startclip ()

I have successfully converted this pdf without 26 pages. But converting process is automatic and i can`t handle each pdf file manualy.

I have looked through these pages, but found nothing. Some have almost no graphic or text, some are full of it.

If it`s pdf problem - i have to know how to avoid this error.

Try running it through,

GNU Debugger:  http://www.gnu.org/software/gdb/download/

( gdb should already be on your system )

or,

Valgrind:            http://valgrind.org/

Might give you a clue as to what is happening.

Segfault is a memory access error.

   http://en.wikipedia.org/wiki/Segmentation_fault

Are you perchance using a VP environment with restrictive memory?
Does this 34MB file
( which I have not attempted to download ) have a large number of
pages?  What happens if
you selectively choose the pages, avoiding the problem one(s)?

HTH.  Thoug maybe not!

Big file, with complex graphics?
