Public bug reported:
Try running `colordiff -u pulseaudio_output pulseaudio_output2`several
times and look at the end of output. You might see following:
<code>
...
- userdata=0x6338a0) at pulsecore/pdispatch.c:241
-#6 0x00007f84fe613163 in pstream_packet_callback (p=0x63c460,
- packet=0x6b8410, creds=0x63c5b0, userdata=<value optimized out>)
+ userdata=0x634b40) at pulsecore/pdispatch.c:241
+#6 0x00007ff134f6f163 in pstream_packet_callback (p=0x64a720,
at pulsecore/protocol-native.c:3105
...
</code>
or following:
<code>
- userdata=0x6338a0) at pulsecore/pdispatch.c:241
-#6 0x00007f84fe613163 in pstream_packet_callback (p=0x63c460,
- packet=0x6b8410, creds=0x63c5b0, userdata=<value optimized out>)
+ userdata=0x634b40) at pulsecore/pdispatch+#6 0x00007ff134f6f163 in
pstream_packet_callback (p=0x64a720,
+ packet=0x639a60, creds=0x64a870, userdata=<value optimized out>)
at pulsecore/protocol-native.c:3105
</code>
and eventually you might see correct result:
<code>
- userdata=0x6338a0) at pulsecore/pdispatch.c:241
-#6 0x00007f84fe613163 in pstream_packet_callback (p=0x63c460,
- packet=0x6b8410, creds=0x63c5b0, userdata=<value optimized out>)
+ userdata=0x634b40) at pulsecore/pdispatch.c:241
+#6 0x00007ff134f6f163 in pstream_packet_callback (p=0x64a720,
+ packet=0x639a60, creds=0x64a870, userdata=<value optimized out>)
at pulsecore/protocol-native.c:3105

With plain `diff -u pulseaudio_output pulseaudio_output2` I never
experience such problems. Looks very much like there is some race
condition or memory corruption somewhere in colordiff script or perl
itself.
I use Ubuntu 8.04 x86_64.
colordiff version: 1.0.6-2
perl-base version: 5.8.8-12
