egcs-200000218: Segmentation fault in cc1

[Andris Pavenis <andris at stargate dot astr dot lu dot lv>]

I tried to compile BYTE benchmarks with gcc-2.96 20000218 and got internal
compiler error (coredump from cc1) when compiling nbench1.c.
Target is  i586-pc-linux-gnu. Preprocessed source attached

I had some .h files in MS-DOS format (\r\n at end of lines). But anyway cc1
should not crash... . After fixing .h files there were no more crash.
