Hi, I have OCAMLRUNPARAM set to b=1 and have compiled and linked with the
-g flag. I am doing linking with gcc because I have a C main and C
objects. The Caml code is compiled with the -output-obj flag to create a
.o that gcc links with. Unfortunately, I'm not seeing exception stack
traces for uncaught exceptions. For example, I get:

Fatal error: exception Invalid_argument("String.get")
(Program not linked with -g, cannot print stack backtrace)

Is there a way to solve this while continuing to use -output-obj to
generate a C-like object for gcc to link against ?

Thanks!
Lex

This is a known limitation of -output-obj: the debug info that is used
to generate stack backtraces is not included in the generated object file.

No, not currently.
