Load the program in gdbpas. Put a breakpoint on HandleErrorFrame (with the
command "b HANDLEERRORFRAME", caps are important). You can set command
line parameters using "set args para1 para2 ...". If not all of the
sources are in one directory, you can add directories that gdbpas has to
search sources in using "directory dir1;dir2;dir3;...".

Next, type "run". When the breakpoint is hit, type "bt" (backtrace).
