Again, my foo.pir is
.include "datatypes.pasm"
.sub test :main
# load library
.local pmc libnci_test
libnci_test = loadlib "libnci_test"
unless libnci_test goto NOT_LOADED
print "libnci_test was successfully loaded\n"
# calling a function in libnci_test
.local pmc nci_c
dlfunc nci_c, libnci_test, "nci_c", "c"
.local int nci_c_out
( nci_c_out ) = nci_c( )
print nci_c_out
print "\n"
.end
and now compiled with dmalloc.
Here is a backtrace... it might be readable by people who knows parrot
internals.
Also, as I'm not very used to use gdb, if I can give more information,
let me know.
Cheers,
Thanks
