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
