I bet the curse is a BLODA

also as I noted that the loading address of your DLLs is **very** low

my pc:
$ grep cygwin1.dll graph.strace
--- Process 84828 loaded D:\cygwin64\bin\cygwin1.dll at 0000000180040000

your strace

$ grep cygwin1.dll temp.txt
--- Process 3080 loaded C:\cygwin64\bin\cygwin1.dll at 0000000000ce0000
--- Process 3080 loaded C:\cygwin64\bin\cygwin1.dll at 0000000000ee0000
--- Process 3080 loaded C:\cygwin64\bin\cygwin1.dll at 00000000014f0000

can you exclude the AV from your cygwin directory ?
