GDB's `bt' implementation has nothing to do with Cygwin's capability to walk a stack. Cygwin only has limited capabilities there which are used to create the stackdump file, see the stack_walk class in exceptions.cc: https://sourceware.org/git/gitweb.cgi?p=3Dnewlib-cygwin.git;a=3Dblob_plain;= f=3Dwinsup/cygwin/exceptions.cc=20 If you want to create a backtrace(3) function set for Cygwin, feel free: https://cygwin.com/contrib.html I'm certainly not averse to patches...
