Bug#530377: libarts1c2a: Error with 32-bit binaries on x86-64 arch

Package: libarts1c2a
Version: 1.5.9-3
Severity: normal
Tags: patch

On x86-64 architecture, the script /usr/bin/artsdsp tries
to preload some libraries in /usr/lib when the executable is
32-bit. The problem lies when /usr/lib contains 64-bit libraries
(which is the case most of the time with x86-64 architecture).
I suggest to add a check for the 32-bit case, along the lines of
the attached patch.

The patch should not introduce regressions: if binary is 32-bit
and /usr/lib/libarsdsp.so.0 is 64-bit then it won't load. In that
case, the fact that /usr/lib32 exists or not is not really relevant.
The only case in which the patched script could fail while the
original would not is (I think) the following:

* 32-bit executable
* single_thread is 1
* /usr/lib/libartsdsp.so.0 is 64-bit
* /usr/lib/libartsdsp_st.so.0 is 32-bit

Since the last two lines are rather silly, I think it is not
relevant (otherwise I can patch the script further, but it will
look even worse).

The test can probably made better. In particular awk is probably
overkill (cut -f3 -d\  is another solution, other exist,
including using set `file -L ...` as above).
