>Environment:
System: SunOS turing 5.7 Generic_106541-20 sun4u sparc SUNW,Ultra-Enterprise
Architecture: sun4
host: sparc-sun-solaris2.7
build: sparc-sun-solaris2.7
target: sparc-sun-solaris2.7
configured with: ../gcc-3.1/configure --prefix /home/oneill/gcc
>Description:
Compiler ICEs on Legal (if somewhat twisted) C++ code. The test-case
ICEs on all platforms tried (i386-redhat-linux, powerpc-apple-darwin5.5,
and sparc-sun-solaris2.7), and on versions 3.0.x, 3.1 and the 20020624
3.1.1 prerelease, although it was derived from code that only ICEd on
powerpc-apple-darwin5.5.
Problem does not occur with Red Hat's 2.96RH version or the 2.95.x series.
>How-To-Repeat:
Compile the following code:
template<int size>
struct Foobar {
// Contents irrelevant
};
template <typename A>
struct Wrapper {
// Contents irrelevant
};
template <typename A>
Foobar<sizeof(Wrapper<A>)> *
compiler_bug (A)
{
return 0;
}
int main()
{
compiler_bug(1);
}
>Fix:
Unknown.
