Bug 40415 – xpdf crashes when moving subwindows

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description G.P. LeChuck 2004-02-04 15:07:14 UTC]

Hi,

xpdf 2.03 crashes when any of the subwindows it displays are moved 
to reveal what's underneath.


Reproducible: Always
Steps to Reproduce:
1. Start xpdf <pdffile>
2. press "o" (file open window appears)
3. move file open window to see what's under it

Actual Results:  
There's a black rectangle in the area where the file open window first
opened. After dropping the window on it's new location, 
"Segmentation fault" is printed and xpdf quits.


Expected Results:  
No segmentation fault.


Adding "-fPIC" to CXXFLAGS solved it for me. Perhaps the ebuild should
be extended in this manner.

Your CFLAGS are very strange and in no way supported. Please try to build with the default CFLAGS, if it still happens it is indeed a bug.
