I'm curious, was the initialization truncate_(max_streamsize()) producing any warning on your platform ?
Strangely, no. g++ is usually pretty good at diagnosing this sort of problem. Trying this test program on two different compilers reveals somethig odd though: #include <iostream> int main() { std::streamsize const a(1); int const b(a); std::streamsize c(1); int const d(c); std::cout << "sizeof(a) == " << sizeof(a) << ", sizeof(b) == " << sizeof(b) << ", sizeof(c) == " << sizeof(c) << ", sizeof(d) == " << sizeof(d) << std::endl; return 0; } Compiling it with g++ 3.3 on an Alpha running linux: aleem@thorax:aleem$ g++ -W -Wall -pedantic -o trial trial.C aleem@thorax:aleem$ ./trial sizeof(a) == 8, sizeof(b) == 4, sizeof(c) == 8, sizeof(d) == 4 No warnings :-( Compiling it with DEC/Compaq/HP cxx 6.3 on an Alpha running tru64 unix: aleem@pneumon:aleem-> cxx -std strict_ansi -w0 -o trial trial.C cxx: Info: trial.C, line 8: conversion to integral type of smaller size could lose data int const d(c); --------------------^ cxx: Info: trial.C, line 6: variable "b" was set but never used int const b(a); ------------------^ cxx: Info: trial.C, line 8: variable "d" was set but never used int const d(c); ------------------^ aleem@pneumon:aleem-> ./trial sizeof(a) == 8, sizeof(b) == 4, sizeof(c) == 8, sizeof(d) == 4 A couple of spurious warnings, but at least it also warns about the assignment of the non-const 'c' to an int. All very odd.
Anyway, I fixed it in CVS (expect some delay for change to appear in the anonymous CVS).
Thanks for reporting this bug, with so much precision !
My pleasure. Angus
