Yes there is.

The compiler must compiled with the debugging information, or the '-g'
flag. This is not the default.

First, delete or rename the old TC binary.

Compile the compiler 'htcobol' using the debug flag '-g'.

This can be done using the 'configure --enable-debug-all' flag, or by the
manual addition of the '-g' flag to the 'compiler' make files.

Copy or install the new compiler binary.

Now use GDB to trace execution as follows.

$gdb htcobol
(gdb) r -P -v source.cob
(gdb) ...
(gdb) ba
(gdb) q

This will normally give you the source file and line were the segmentation
fault occurs.

Alternatively you could send me the source code.

Hope this helps.
