Compiler error on alphaev56-dec-osf4.0b

[Dan Suson]

I am trying to get some c++ code to compile on an alpha under
egcs-1.0.3a.  The first subdirectory of code builds and creates a
library okay, but when it hits the first file in the second subdirectory
I get the following error:

mips-tfile, /tmp/ccaamwAa.s:336 String too big (4248 bytes)
line:    #.stabs "__insert::1497=##1498=xs__rb_tree_iterator<pair<const
unsigned int,REQ_bit *>,pair<const unsigned int,REQ_bit *> &,pair<const
unsigned int,REQ
                     .
                     .
                     .

I have been able to get the same code to compile under egcs on a Pentium
running linux, so I don't think it is the source code.  How can I fix
this?
