I think it'd be easier to "catch" the problem rather than to chase it by running all commands under the debugger.

For that, define the CYGWIN environment variable (via Windows) as:
error_start=c:\cygwin64\bin\dumper.exe

(that assumes that Cygwin is installed at c:\cygwin64)

Then whenever the abort occurs, you'll have a core file, which can be loaded into GDB and the backtrace investigated.
Something like this:

$ gdb /path/to/command command.core
(gdb) where

My $.02,
