This is the grep executable that is shipped as part of the Git distribution for 
Windows [1] [2].

Indeed I can reproduce the error exactly as shown, in a Windows environment 
with the latest Git 2.29.2 installed:

D:\>echo abc | "C:\Program Files\Git\usr\bin\grep.exe" -iqF d
      0 [main] grep 855 cygwin_exception::open_stackdumpfile: Dumping stack 
trace to grep.exe.stackdump

D:\>type grep.exe.stackdump

Unfortunately the stack trace isn't really helpful. :-)

Keith, I suggest you report this on the GitHub issue tracker of git-for-windows
