Subject:	ld crash when building emu387.dxe
Reply-To:	djgpp-workers AT delorie DOT com

Hello.

I seem to be experiencing crashes, when trying to build emu387.dxe. The traces
below are with gcc, binutils, fileutils, sh-utils and textutils built against
CVS from a few days ago with my multiple-consecutive-slash patch. Apart from
this crash, everything seems to be working OK.

Please note that I also get this crash in another tree, which is built with
stock versions from Simtel.NET. Both trees have been built with -g with gcc
3.2.1 - DWARF-2 debugging information.
