Re: the mangling of ‘va_list’ has cha nged in GCC 4.4

[peter green]

I have recently came across .symver directive [1][2] that is more 
straightforward way to achieve the same thing. In that case, only source file 
(.cpp) needs to be changed. For example:

Isn't it also nessacery to bump shlibs (for libraries that aren't using symbols 
files), otherwise a new binary could be installed with an old library and hence 
be left broken.

Re: the mangling of ‘va_list’ has cha nged in GCC 4.4

[Riku Voipio]

Hi debian-release,

There is a major problem with gcc 4.4 and armel - the ABI of va_list 
changed (for c++ libraries). We need to decide one of the following:


1) library package name rename (like c2a rename previously)

+ the right thing to do
+ partial upgrades work as expected
- Some hassle for !armel sid users while transition happens
- Quite a bit of extra work for many unrelated people (maintainers, 
ftp-masters..)


2) binNMU campaign

- during the upgrade armel sid users packages will be broken (some 
already are)

- even after, partial upgrades for armel users risk broken setups
+ does not disturb !armel users
+ no extra work for others but porters and release team

3) g++ downgrade or reverting to the old va_list mangling within g++4.4 
for armel


- A bunch of libraries and binaries have already been compiled with the 
new g++

- I think this is a bad idea anyway

What way should we proceed? The list of supposedly affected packages 
follow (haven't had time to check myself).

Indeed, I believe that the following binary packages, which ship 
shared libraries, are affected (i.e. linking to them will cause 
problems):
