Description Jef Spaleta 2002-03-28 02:18:51 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 Galeon/1.2.0 (X11; Linux i686; U;) Gecko/20020314

Description of problem:
the pnmflip command is not behaving properly when using the rotate switches -r90
-r180 -r270, the -lr -tb switchs seems to work fine

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. pick your favorite jpg image
2. jpegtopnm whatever.jpg |pnmflip -r90 > whatever.pnm
3. the pnmflip process segfaults

Actual Results:  pnmflip errors out with a segfault

Expected Results:  pnmflip should have created a resultant pnm file rotated
according to the -r switch used.  this use to work. I have a program called
Gallery installed that makes use of pnmflip for image manipulations via the web.
 Old versions of the netpbm-prog package worked just fine.

Additional info:

No useful error messages just a segfualt statement

I saw this problem ages ago, when playing around with vidwhacker.  Rebuilding
the package from the source RPM fixed it (with gcc 3 installed) and does so
now.  I think this is a miscompilation problem with gcc 2.96.
Comment 3 Phil Knirsch 2002-04-09 10:36:10 EDT
OK, this is sort of a compiler optimizer bug. I've fixed it now in the source
and even optimized the whole thing by doing so. :-)

Will suggest this fix to the maintainer of the netpbm package upstream.

Read ya, Phil

The source was valid though, if a little ugly :o)
Should I go log this against gcc or has that been done internally?
