I can reproduce this by simply issuing: doveadm reload GNU gdb (GDB) 7.0.1-debian Copyright (C) 2009 Free Software Foundation, Inc.

Ive been getting a LOT of these errors since 1.1.2: So far ive seen this with 1800 customers, and we're getting active complaints about errors in imap clients. When I check the users log I always see this error.. This always happens with COPY commands in Squirrelmail. Sep 2 20:09:35 userimap4.xs4all.nl dovecot: IMAP(xxxxxxx):

Someone is trying to work on HLVM with me but they're hitting a problem that we have not been able to resolve. Specifically, GCC seems to be performing some kind of sanity check for "stack smashing" and is calling abort because it is unhappy with something that the code is doing. However, I am not sure what and cannot reproduce the problem. The stack trace they have given me is:

I run a script that imports a few thousand records into the database. The script runs once for each of several XML files. What it does is parse the XML and for each element of a certain type creates a record in a rails database that gets indexed with acts_as_ferret. This worked fine before but today after a few files (70000 records) this started to happen for any file I tried:

I have a Rails 1.2.3 app (due for an update, I know) running on a Mongrel 1.1.4 behind Apache 2.2.3 mod_proxy on Debian 4.0. It keeps hanging up for no reason I can tell. I have tried everything that anyone has ever hinted at being a solution for this problem: - The application doesn''t use MySQL, so setting the connection timeout won''t help. - Using AR not PStore for sessions. -

Some more information: the issue has just occurred, again on an instance without the "service_count = 0" configuration directive on pop3-login. I've observed that while the issue is occurring, the director process goes 100% CPU. I've straced the process. It is seemingly looping: ... ... epoll_ctl(13, EPOLL_CTL_ADD, 78, {EPOLLIN|EPOLLPRI|EPOLLERR|EPOLLHUP, {u32=149035320,

Hi Chandler, I feel like this conversation has come full circle. So to ask again: how does one force CMOV to be emitted? You suggested “__builtin_unpredictable()” but that gets lost in various optimization passes. Given other architectures have CMOV like instructions, and given the usefulness of the instruction for performance tuning, it seems like a direct intrinsic would be best. What am I

I’m struggling to find cases where __builtin_unpredictable() works at all. Even if we ignore cmp/br into switch conversion, it still doesn’t work: int test_cmov(int left, int right, int *alt) { return __builtin_unpredictable(left < right) ? *alt : 999; } Should generate: test_cmov: movl $999, %eax cmpl %esi, %edi cmovll (%rdx), %eax retq But currently generates: test_cmov: movl $999,
