Where do core dumps in Cygwin go? ulimit -c is set to unlimited in
bash, but on SEGV no core dump is created in cwd.
I need a stack trace for randomly occurring SIGSEGV of an application,
but cannot just instrument every invocation.

Read:

However, unfortunately, cygwin 3.4.8 is missing dumper.exe.
Please use latest cygwin 3.5.0 (Test) or cygwin 3.4.7 so far.

Why? Will this be fixed for cygwin 3.4.8-2?
@Corinna Vinschen ?

How do I downgrade to cygwin 3.4.7 in the gui installer?

1) Run setup-x86_64.exe
2) Proceed to the "Select package" menu.
3) Select "Full" in "View" select box.
4) Input "cygwin" into "Search" input box.
5) Change "New" column of "cygwin" package from "Keep" to 3.4.7-1.
6) Proceed the setup.

"accidentally missing"

This was due to an error in our build scripts (which was not noticed
until after the fact)
It will be present in 3.4.9
