Bug 285436 – app-text/xpdf-3.02-r3 -reload crashes

• Product: Gentoo Linux
• Status: VERIFIED TEST-REQUEST

xpdf -remote doc file.pdf &
xpdf -remote doc -reload

The second command causes: 
*** glibc detected *** xpdf: double free or corruption (out): 0x080b95a0 ***

valgrind reports it as:

==2504== Invalid read of size 4
==2504==    at 0x40D3DD6: BuiltinFontWidths::~BuiltinFontWidths() (BuiltinFont.cc:39)

It looks like both ~GlobalParamsGUI and ~GlobalParams are calling freeBuiltinFontTables, so the second call is failing.  I'm not sure about the rest of the code, so I don't know if it's necessary to have both objects in xpdf.  By the names of the classes, it seems like it should use one or the other, but not both.

Please try with poppler-0.12.3-r5 and xpdf-3.02-r4 and if it still doesn't work, reopen the bug

Yes, it works now; thanks.
