I also tried gcc-3.0.2 which has same problem: #include <iostream> #include <fstream> int main(void) { unsigned char buffer[2]; buffer[0] = 0; buffer[1] = 1; std::ofstream outfile("outfile"); if (!outfile.good()) { std::cerr << "Error Opening Output File.\n"; return 1; } outfile.put(buffer[0]); //The following line will not compile under gcc-3.2 when //buffer is of type unsigned char[], but will if it is //of type char[]. This code compiled fine prior to //gcc-3.0. outfile.write(buffer,2); outfile.close(); return 0; } >How-To-Repeat: Built the attached program using gcc-3.2, gcc-3.0.2, and possible other gcc-3.x compilers. >Fix: >Release-Note: >Audit-Trail: >Unformatted: ----gnatsweb-attachment---- Content-Type: application/octet-stream; name="main.cpp" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="main.cpp" I2luY2x1ZGUgPGlvc3RyZWFtPgojaW5jbHVkZSA8ZnN0cmVhbT4KCmludCBtYWluKHZvaWQpCnsK ICB1bnNpZ25lZCBjaGFyIGJ1ZmZlclsyXTsKICBidWZmZXJbMF0gPSAwOwogIGJ1ZmZlclsxXSA9 IDE7CiAgc3RkOjpvZnN0cmVhbSBvdXRmaWxlKCJvdXRmaWxlIik7CiAgaWYgKCFvdXRmaWxlLmdv b2QoKSkKICB7CiAgICBzdGQ6OmNlcnIgPDwgIkVycm9yIE9wZW5pbmcgT3V0cHV0IEZpbGUuXG4i OwogICAgcmV0dXJuIDE7CiAgfQogIG91dGZpbGUucHV0KGJ1ZmZlclswXSk7Ci8vVGhlIGZvbGxv d2luZyBsaW5lIHdpbGwgbm90IGNvbXBpbGUgdW5kZXIgZ2NjLTMuMiB3aGVuIGJ1ZmZlciBpcyBv ZiB0eXBlCi8vdW5zaWduZWQgY2hhcltdLCBidXQgd2lsbCBpZiBpdCBpcyBvZiB0eXBlIGNoYXJb XS4gVGhpcyBjb2RlIGNvbXBpbGVkCi8vZmluZSBwcmlvciB0byBnY2MtMy4wLgogIG91dGZpbGUu d3JpdGUoYnVmZmVyLDIpOwogIG91dGZpbGUuY2xvc2UoKTsKICByZXR1cm4gMDsKfQo=
