Boostrap failure of CVS version since April 29th

Tue May 2 04:44:00 GMT 2000

Already for some days I'm getting crash while bootstrapping current CVS
version of gcc-2.96. Last successfull bootstrapping was at April 28.

System: Pentium 200MMX, Linux-2.3.99pre6, binutils-2.9.1.0.37, 
	I used gcc-2.95.2 for bootstrapping gcc

Configure options:
	--prefix=/usr --enable-shared --with-gnu-ld --enable-threads --verbose
