Bug #: 13567
Summary: overflow in emulated timer_settime() on Linux/HPPA at
least
Product: glibc
Version: 2.4
Status: NEW
Severity: normal
Priority: P2
Component: libc
AssignedTo: drepper.fsp@gmail.com
ReportedBy: P@draigBrady.com
Classification: Unclassified
Created attachment 6150
--> http://sourceware.org/bugzilla/attachment.cgi?id=6150
An strace of the problematic timeout run
When testing recent coreutils releases on parisc linux, it was noticed
that timer_settime($large_num) would cause the timer
to immediately fire when $large_num spanned the 2038 boundary.
This function is used by the `timeout` utility.
Seems to me that time_t is overflowing,
and being interpreted as a negative number.
Note time_t is signed 32-bit on this platform.

Carlos, you should probably look at this, though
linuxthreads-0.10 by Xavier Leroy
libthread_db work sponsored by Alpha Processor Inc
in the report suggests it may be specific to Linuxthreads, which is no longer a
supported configuration.
