Internal Compiler error with C++

["Olivier Bonningues" <bonnin at nortelnetworks dot com>]

Hello,

We use the cygnus C++ compiler for PowerPC in the Tornado environnement of
WindRiver System compagny.

We have an "Internal compiler error" with the compiler used in Tornado2.
This problem does not exists in Tornado1.
Here enclosed you can find an example of C++ code which generates the problem.

The 2 versions of compiler are
for Tornado2 (with problem)
Reading specs from /bt2vobs/tools/WRS5/tornado/host/sun4-solaris2/lib/gcc-lib/powerpc-wrs-vxworks/cygnus-2.7.2-960126/specs
gcc driver version cygnus-2.7.2-960126 egcs-971225 tornado 2.0 executing gcc version cygnus-2.7.2-960126
for Tornado1
Reading specs from /bt2vobs/tools/WRS5/tornado/host/sun4-solaris2/lib/gcc-lib/powerpc-wrs-vxworks/cygnus-2.7.2-960126/specs
gcc version cygnus-2.7.2-960126

It is difficult to get information from WindRiver about this problem, which is critical for us.
Do you know this problem ?
Is it fixed and solved in a new release of the compiler ?
Is there a workaround ?

It will be very hepful to us to have any information about this problem.
Thanks for your answer.
Regards,
Olivier Bonningues
