Thank you for sharing rr in the first place! It looks like a very
promising and useful tool for us!
I'm trying out rr with -m32 apps on my x86_64 kernel. The "rr record"
command always succeeds, but "rr replay" always gives the following
error and hangs:
(gdb) b sre_vm_pike_add_thread
Breakpoint 1 at 0x804f1e0: file src/sregex/sre_vm_pike.c, line 760.
None) (task 18985 (rec:18977) at trace line 18)
-> Assertion `0' failed to hold: Replay got unrecorded signal 11
Attach to the rr debug server with this command:
target remote :18985
I installed rr via the fedora binary package just yesterday via
wget http://rr-project.org/releases/rr-1.0.0-Linux-$(uname -m).rpm
sudo rpm -i rr-1.0.0-Linux-$(uname -m).rpm
And below is more info for my system:
$ uname -a
Linux w530 3.10.16 #6 SMP Wed Nov 6 12:32:21 PST 2013 x86_64
x86_64 x86_64 GNU/Linux
$ grep Core /proc/cpuinfo|head -n1
model name : Intel(R) Core(TM) i7-3920XM CPU @ 2.90GHz
I tried both LuaJIT (http://luajit.org/download.html ) and my own
sregex library (https://github.com/agentzh/sregex ).
Any help on debugging this further will be highly appreciated :)
