RE: Cygwin X applications do not launch

["Jones, Michael" <michael dot jones at roke dot co dot uk>]

Hi Marco,

You are correct!
With AV disabled, everything seems to work fine.

I now need to work with our IT guys to figure out how to configure the AV so that it does not interfere.

Many thanks for your help diagnosing the cause of this problem!

Regards,
Mike

Hi Mike,

I think the AV is interfering.
A lot of Windows DLL's are loaded at very low addresses:

--- Process 10964 created
--- Process 10964 loaded C:\Windows\System32\ntdll.dll at 0000000077860000
--- Process 10964 loaded C:\Windows\System32\kernel32.dll at 
0000000077740000
--- Process 10964 loaded C:\Windows\System32\KernelBase.dll at 
000007fefd7e0000
--- Process 10964 loaded 
C:\Windows\System32\tmumh\20019\AddOn\6.80.0.1007\TmUmEvt64.dll at 
000007fefc290
000
--- Process 10964 loaded C:\Windows\System32\psapi.dll at 0000000077a00000
[cut...]
--- Process 10964 loaded C:\Windows\System32\rpcrt4.dll at 000007fefdfc0000
--- Process 10964 loaded 
C:\Windows\System32\tmumh\20019\TmMon\1.6.0.1195\tmmon64.dll at 
0000000075070000
--- Process 10964 loaded C:\cygwin64\bin\cygwin1.dll at 0000000180040000


for ntdll.dll for example:
0000000077860000 your system
00007ffd81700000 my system

and the exception at the end of strace is in that area
00000000779332ca

   160  398012 [main] gedit 10964 sigprocmask: 0 = sigprocmask (0, 0x0, 
0x6000A2AA0)
--- Process 10964 thread 8560 created
--- Process 10964, exception 80000001 at 00000000779332ca
--- Process 10964 thread 12024 exited with status 0x80000001

can you try without with AV or excluding the "C:\cygwin64" directory ?

Regards
Marco
