Package: procinfo
Version: 18-1
Severity: important
When running on a modern server with many interrupts, procinfo
segfaults.
I have one MSI interrupt which is assigned number 1269. This causes
/proc/stat to have a very long 'intr' line since it has to show that
many interrupts. procinfo assumed that no line in /proc/stat would ever
exceed 1024 characters, so when it reads the line it only reads part of
it, and as a result ends up thinking there are only about 500 interrupts
in the system, so later when it tries to print the value for interrupt
1269, it segfaults.
The simplest fix is to increase the size of 'line' on procinfo.c:80 to
something much larger, I tried 102400 instead of 1024 and it works fine,
although perhaps a better algorithm could be determined.
With the current size, it will always segfault on a machine like this
one. This appears to also affect procinfo in Lenny. Of course on most
machines it will work fine since most have a much lower number as their
highest interrupt.

Unfortunately release team rejected my freeze exception request.
