Subject: multiple dll's cause app to hang 
Content-Type: text/plain; charset=us-ascii; format=flowed
Content-Transfer-Encoding: 7bit

dear all

I have what I would call a major problem.
(common across all machine types I have here)

when I compile a application such as sed and cygwin1.dll everything 
works but if I try and mix my dll with the net version it hangs

say I have a normal net install

I compile cygwin prefix=/install
I compile sed prefix=/install

now if I remove cygwin1.dll from /install/bin/ sed executes fine
if I replace /bin/cygwin1.dll with my compiled version from /install 
everything works

but if I mix the two it just hangs and causes DrWatson to complain if I 
ctrl-C it.

(this is not common to sed ps.exe fails also)


I have strace'd it and it seems to do with the shared memory. As it does 
not even get to executing the program I put in some debug prints so that 
I could find out the mode but I am unsure of what's going on after the 
_P_OVERLAY.

so what this says to me is that if someone installs a cygwin net over a 
different release then it will invalidate the previous install

should I just change the version numbers ? as they are the same at the 
moment, so they don't try and share memory and if so the API version 
number or the major

what's the sensible way of going about this ?

or is something really broken ?
(its not like I am changing the source or using custom programs but the 
ones supplied with cygwin)

regards

john jones

p.s. for your viewing pleasure I have attached the snippets from strace 
and cygcheck
