I am trying to open a pdf file via evince,after I open it and go through the page,Program suddenly jumped out and following error appears in shell ''bogus memory allocation size'' how it can be fixed?
You could try ghostscript or Okular or kpdf or another free viewer.
You could install Foxit or Adobe reader proprietary software for Linux.
You could see if there are updates available for your RHE5 system.
You could report the bug and wait for Red Hat to fix it. :)
