Internal compiler error in g++ from GCC2.95.2

g++ 2.95.2 aborts unceremoniously when attempting to compile this
simple file:
class StringParser {
public:
StringParser() { }
~StringParser() { }
double& parse(const char* s, double& x) { return x=basicparse(s,x); }
template<class T> T& basicparse(const char* s, T& x) { return x; }
};
The code compiles fine under "gcc version egcs-2.91.66 19990314/Linux
(egcs-1.1.2 release)" on the same machine. The command line and
output are attached; the preprocessor output was the same as the above
except that it was prefixed with '# 1 "bug.c"'. Should this code
prove useful as a test case, I hereby place it into the public domain
for you or anyone else to use for whatever purpose you or they see fit.
Thanks,
Jim
