First, please tell us whether the SEGVs happen even if you build the Cygwin Emacs with the versions of GCC that are considered ``safe'' (in the sense that other versions are known to produce a binary the crashes almost instantly). See the entry in PROBLEMS whose header is "Building the Cygwin port for MS-Windows can fail with some GCC version". Also, please make sure you don't build the Cygwin port with GTK+, as this configuration is known to crash on Cygwin (again, see PROBLEMS). If the crashes happen in a binary that is nether built with GTK+ nor compiled by ``unsafe'' GCC versions, then yes, we would like to try to debug this. Unfortunately, none of the Emacs maintainers use Cygwin, so all we can do is ask you to investigate and suggest ideas for how to fix it. Thanks.
