The dreaded STATUS_ACCESS_VIOLATION

[David]

Hi all! I know that STATUS_ACCESS_VIOLATION is a common issue with
Cygwin, but I'm at the end of my rope. I only get this problem with
mintty on my bare-bones Cygwin 1.7.15-1 installation. I added another
terminal (rxvt) just to make sure it would run, and it does. I've
tried rebaseall, I've tried peflagsall. Mintty produces the following
stack dump:

---------------------------------------------------------------------------------------------
Exception: STATUS_ACCESS_VIOLATION at eip=61004D96
eax=0000029C ebx=61244000 ecx=00000000 edx=61245F0C esi=FFFFFFFF

I'm running Windows 7 64-bit in a corporate environment. I've tried
shutting off DEP to no avail. Am I the only one having this issue?
Can anyone help me troubleshoot?

Apologies for the late reply.

Can you add some details about when this happens and whether it is
reliably reproducible? Which version of mintty are you using, and is
it the one that ships with Cygwin? Does the problem still happen with
Cygwin 1.7.16 released yesterday?

You could build a debug version of mintty by unpacking the sources and
building it like this:

make debug=1

Then, if you still get a stackdump, you can use the addr2line utility
to translate function addresses from the stackdump to source
locations, by running this and then pasting in addresses:

addr2line -e mintty.exe

Any luck with this? I'm having the same issue in a similar setting. Windows 7 64-bit Cygwin 1.7. I tried adding mintty.exe to DEP, to no avail.

Thanks for any suggestions.
