I reproduced a nearly the same operations that performs cl.exe. char data[68100 + 65536]; char buf[sizeof(data)]; for (int i = 0; i < sizeof(data); i++) data[i] = rand(); FILE* f = _wfsopen(L"test.bin", L"wb+", 64); rewind(f); fwrite(data, 1, 68100, f); // Following calls possible corrupt buffer rewind(f); fread(buf, 1, 32512, f); fread(buf, 1, 4096, f); fread(buf, 1, 28672, f); fread(buf, 1, 4096, f); fread(buf, 1, 29948, f); // Following call causes wrong buffer flushing fwrite(&data[68100], 1, 65536, f); fclose(f); f = fopen("test.bin", "rb"); fread(buf, 1, sizeof(buf), f); fclose(f); printf("Memcmp: %d\n", memcmp(data, buf, sizeof(buf))); -- Do not reply to this email, post in Bugzilla using the above URL to reply.
