Package: libc6
Version: 2.5-7
Severity: important

Today I saw this error for the second time on my hppa box running the 
2.6.18-parisc64-smp kernel:
cat: error while loading shared libraries: internal error: symidx out of 
range of fptr table

People on #parisc say that this is a glibc issue:
<patofiero> fjp, I have not looked at the current sources in debian glibc, 
but in general there *are* functions which are supposed to be atomic but 
are not. These failures can cause a "symidx out of rang of fptr table" 
error.
<patofiero> fjp, The failure is in glibc.
<patofiero> fjp, It's using non-atomic implementation of compare and swap. 
However, the problem is systemic of a kernel that doesn't have atomic 
helper functions.
<fjp> I'm running 2.6.18-4-parisc64-smp
<patofiero> fjp, smp is more likely to trigger the error.
<patofiero> fjp, You have the atomic helper routines present in your 
kernel.
<patofiero> fjp, The glibc you have just isn't using them.
