valgrind can be another option for tracing the problem. Just install valgrind
and issue the command
valgrind /usr/bin/gretl_x11 your_script.inp
Execution will be _very_ slow, but if you get a crash you should receive a
list of the internal functions that led to it.
Valgrind can be very helpful in general, but this case is special.
I'm pretty sure it's not a "true" crash -- I believe that the libR
code is calling abort() when it can't find Renviron (because it
doesn't know the value of R_HOME). And when abort is called by a
library, the program that loaded the library is automatically
terminated. This is consistent with the fact that Ignacio couldn't
get a backtrace from gdb: gretl didn't segfault, it just exited.
