[Bug java/20469] New: gcjh does not rename Java variables named NULL

2005-03-14 Thread strk at keybit dot net 
headers generated by gcjh contains class members (didn't check about other
kind of objects) named 'NULL'. This is the name used in Java sourcecode, but
cannot be safely used in C++ headers as NULL is always (or often?) defined.

g++ error raised when including the produced headers is:

error: expected unqualified-id before numeric constant

[Bug c++/39623] New: Optimizer changes return from htons(uint16)

2009-04-03 Thread strk at keybit dot net 
The bug is known to occur with the following versions:
 - gcc version 4.3.2 20081105 (Red Hat 4.3.2-7) (GCC)
 - g++ (Ubuntu 4.3.2-2ubuntu11) 4.3.3 20090111 (prerelease) 

The symptom of the bug is that when you use -O2 htons(short) returns
'unsigned int' (32 bit) rather then the expected 16bit value.
With no optimization it returns the correct 16bit.

I'll attach a testcase.

You mean I should file a bug against libc ? Or that it's a non-bug ?
The htons() manual page states it'd return a short...
