pcsx2 crashes with an unhandled page fault

[GoogleCodeExporter]

The game runs mostly fine and I'm nearly through and the crash only happend 
twice.
This here is a similar bug http://code.google.com/p/pcsx2/issues/detail?id=1296 
but was resolved due to a driver problem.
I use the software renderer of GSdx.
The bug is not easily reproduceable because I'm not sure what the trigger is.
It happend once when fighting Kurt and the first time was against the dragon 
form of Maleficent (I think or it was Kurt one of the two)
Sadly I didn't start pcsx2 from a terminal so I can't give any additional 
information except for the output from the gui that doesn't contain a 
stacktrace.

/tmp/yaourt-tmp-thomas/aur-pcsx2-svn/src/pcsx2/common/src/Utilities/Linux/LnxHos
tSys.cpp(64) : assertion failed:
    Function:  void SysPageFaultSignalFilter(int, siginfo_t*, void*)
    Thread:    MTGS
    Condition: false
    Message:   Unhandled page fault @ 0x00001a30

Stacktrace:

I'm using archlinux and pcsx2 from svn (5 days ago) 1.1.0.r5821-1.I use the 
software renderer on my intel card of my haswell (lspci says Intel Corporation 
Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller) and my 
kernel is build from git too and maybe a week old.

Without a stacktrace I won't be able to help you (it already difficult with 
one).

Ask your distribution to provide a debug package (or to not strip the symbol).

Yeah sure.It's just hard to reproduce and at the time I only had it compiled 
without debug symbols.Just wanted to open up a bug report so other people could 
maybe find the little knowledge that would be gathered here and post their 
stacktraces here

I'm still a noob using GDB... if you need bt full, let me know... (tried to get 
one, but I didn't see the end of it...)

This was doing making gdb attach into the process and switching to the MTGS 
thread. 

Reproduction?

I use a PS2 controller with Twin Joystick USB adapter. I booted up MGS 3, when 
I got into the forest area I pressed R2 and the crash happened.

@allenskd,

What is your GPU and driver?

Hum it seems to be an aligment issue. Normally storrent parameter must be 16 
Bytes aligned whereas dst is only 8 bytes aligned. Dst is generated by 
glMapBufferRange which is normally 64 bytes aligned but it is only guarantee 
for GL4.2!!!! Seriously they could have put it in GL1.

Normally fixed on the trunk and 1.2.2. Reopen a bug if the crash still exists.
