thanks. so we "guessed" the address of the lib_call function wrongly. how odd. I
assume ./loc2c-test -e testsuite/libexternalvar.so 0x62c libvar does spit out
the location information for libvar?

Could you run stap -vvvvv -p4 -e 'probe
process("testsuite/libexternalvar.so").function("lib_call") { printf("libvar =
%d\n", $libvar); }' to see how/what/where we get that 0x1a70 address in the
first place?
