Internal compiler error in gcc

[Daniel Suson <suson at newton dot tamuk dot edu>]

Dear Sir or Madam,
	I am using the egcs-1.0.3a release on a linux system, kernel
version 2.0.30.  I am trying to compile some c++ code for a project that I
am working on and encountered the following error:


AListBase.cxx: In method `void *& HepAListBase::newInsert(int)': 
AListBase.cxx:31: Internal compiler error. AListBase.cxx:31: Please submit
a full bug report to `egcs-bugs@cygnus.com'. 


The command line generated by the Makefile for this routine is


g++ -I/usr/include/egcs -I..  -g -Wall -ansi -pedantic -Wwrite-strings
-Wpointer-arith -Wnested-externs -W -Woverloaded-virtual
-Wbad-function-cast -O -c AListBase.cxx


I am attaching a copy of the file which generated this error.  Please let
me know what, if anything, I can do to fix or work around this error as
quickly as possible.  If there is other information which is needed,
please contact me at this address.

Thank You,

Dan
