Appears to be due to use of constructor for default value of function argument. >How-To-Repeat: This command line: g++ -c foo.cc -o foo.o -g -MMD -frepo -ansi -pedantic -fshort-enums -W -Wall \ -Wundef -Wshadow -Wpointer_arith -Wbad-function-cast -Wcast-qual -Wcast-align \ -Wwrite-strings -Wconversion -Wsign-compare -Wredundant-decls \ -Wunreachable-code -Wmissing-declarations -Winline -fmessage-length=99999 \ -Werror This is the source code in foo.cc: template <class Arg> class One { public: virtual int Func (int X (0)); }; template <class Arg> int One <Arg>::Func (int X (0)) { return 1; } >Fix: Use int X = int (0) instead. I discovered this using a more complicated type of course, one that had a nontrivial constructor, but the bug shows with int. >Release-Note: >Audit-Trail: >Unformatted:
