bug report (Internal compiler error)

[egcs-bugs@cygnus.com]

Hello I am a student in saga-u (Japan).
I use egcs C++ compiler on sun-sparc-solaris2.6.(egcs version is egcs-2.91.57)
When I try to compile , the compiler invoked "Internal compiler error".
And compiler said I should do bug-report. ^^;;)

However , same files succeed on sun-sparc-sunOS4.1:g++(gcc-2.7.2.1)
                                sun-sparc-solaris2.6:g++(gcc-2.8.1)
The source file is lnMatrix.cc lnMatrix.h , and makefile

-------------------------------lnMatrix.h----------------------------------------
