Bug 19975 – xpdf segfaults on most pdfs (ppc)

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Steven Lucy 2003-04-25 20:51:22 UTC]

xpdf segfaults on most pdfs i try to open on my ppc.  i've tried unmerging
lesstif, unmerging xpdf, remerging openmotif, and merging xpdf, but to no avail.
i've also tried CFLAGS="":  same thing.  some very simple pdfs (like from pdftex)
work fine, but 90% cause a crash.  this is on 2.02 (the only version in portage)

Reproducible: Always
Steps to Reproduce:

tried your pdf here everything is fine, could you strace or catchsegv it please?

[Comment 2 Rajiv Aaron Manglani (RETIRED) 2003-04-27 01:40:05 UTC]

that pdf works just fine for me. i'm using:

CFLAGS="-O3 -pipe -mcpu=750"

Just another "works for me"

here is the strace.  sorry i didn't include it originaly.  i have at one friend
who i (think) is experiencing the same trouble, but he's been out of contact
for the last few days, so i've been unable to verify.  i'll see if i can get him
to post here.

[Comment 5 Steven Lucy 2003-04-27 16:45:11 UTC]

Created attachment 11230 [details]
strace of "xpdf rearrang.pdf"

[Comment 6 Bartosch Pixa (RETIRED) 2003-04-27 22:35:03 UTC]

call it a wild guess, but could you try to remerge freetype ?

[Comment 7 Steven Lucy 2003-04-27 23:48:28 UTC]

remerged freetype -- same problem.

[Comment 8 Justin Blanchard 2003-04-28 00:11:48 UTC]

I'm the friend Steven mentioned. It's totally broken on my (ppc) system too.
My strace isn't identical, but it looks a lot like his.

ok, now there's not much left waht it could be, beside the stuff you already recompiled there's only xfree, gcc, glibc and t1lib, maybe it's t1lib, or maybe
your ghostscript is messed up, but we realy can't reproduce your segfaults.

[Comment 10 Steven Lucy 2003-05-01 03:05:40 UTC]

recompiling t1lib seems to have done the trick.  if justin can replicate
then i guess the problem is solved.  thanks for your help.

[Comment 11 Justin Blanchard 2003-05-01 21:16:07 UTC]

That did the trick for me too.

[Comment 12 Bartosch Pixa (RETIRED) 2003-05-01 22:30:51 UTC]

heh, if it wasn't t1lib i'd realy be lost with no clues left ;)
