It's strange. Looks like there's a bug in your GDB, because it dumps core in this case. I also don't understand why the backtrace ends in the exception handler, it sounds like GDB is not given the first opportunity to handle an exception, as it should? Maybe try upgrading to GDB 8.2, if its Cygwin port is available? Ken, could you please chime in? It is strange that this problem only affects the Cygwin build, and no other bug report points to that change from other GTK builds, including not from other Cygwin users. So it sounds like a Cygwin problem, perhaps triggered by something on Yamaoka-san's machine, but the fact that GDB crashes doesn't allow any reasonable way of investigating the problem past the exception handler. I don't know what to do next.
