Assertion error with -g: abi2_mangler::entity_expression

Question

this happens with both WS6U2 (patched with latest patches) and Forte7EA (latest version)
yet another assertion error when debugging is enabled (-g):
$ /space/opt/SUNWspro/bin/CC -g -c sparcv9/ultrasan/main.cc -o sparcv9/ultrasan/main.o
>> Assertion: unhandled expression in abi2_mangler::entity_expression (../lnk/v2mangler.cc, line 1565)
while processing sparcv9/ultrasan/main.cc at line 0.
$
it compiles okay without warnings when "-g" is removed.
blech

Answer 1

i am using Forte 7: CC: Forte Developer 7 C++ 5.4 Patch 111715-05 2003/02/09
on Solaris 9: uname -rvpmi gives "5.9 Generic sun4u sparc SUNW,Sun-Blade-1000"
with this code snippet, saved as forte_template_expressions.cc:
template < int log2_line_size >
struct IntTemplate {
template < int log2_line_size >
struct IntTemplateArith {
typedef IntTemplate < log2_line_size + 1 > IT ;
IT * it ;
IntTemplateArith (IT * it_) : it(it_) { }
void spam(IntTemplate<6> * it) {
IntTemplateArith<5> tmp(it);
//ends
$ CC forte_template_expressions.cc -c
$ CC forte_template_expressions.cc -c -g
>> Assertion: unhandled expression in abi2_mangler::entity_expression (../lnk/v2mangler.cc, line 1574)

i note that the readme mentions template expressions as buggy:
o Expressions involving non-type template parameters in
the function parameter list for function templates, such
as
template<int I> void foo(mytype<2*I> ) { ... }
but this is not a function template, and anyway it works without debugging enabled.
