[Sbcl-help] SBCL Binary Debugging and FFI

[Volkan Y. <yaz...@tt...>]

Hi,

I'm trying to interface with a foreign C library from SBCL (using CFFI)
and having some troubles while calling the foreign function. The problem
is that the called function skips some portion of the code -- i.e. some
printf() statements get never executed within the code, despite it works
without a problem if I make the same simple call from a C file. I'm not
a C guru but am suspecting some stack re-alignment related stuff. Do you
have any ideas?

To be able to spot the problem, I tried to attach the SBCL session via
gdb but had no success because of signals. Can anybody guide me to debug
the foreign library function while SBCL is making a call to it?


Regards.
