I'm trying to debug firefox and related on ia64. I was told in gecko@ to ask here about analysing core dumps. I rebuilt and reinstalled /usr/src/lib/libthr with DEBUG_FLAGS='-g -O0' What can I get from this trace: http://seis.bris.ac.uk/~mexas/ff-gdb ? I also rebuilt freebsd-gecko/devel/nspr (a development version of port devel/nspr) WITH_DEBUG=. It fails several tests: http://seis.bris.ac.uk/~mexas/nspr-test.log in particular this one: nbconn FAILED nbconn: Assertion failure: (rv == 1) && (pd.out_flags == PR_POLL_READ), at /usr/ports/freebsd-gecko/devel/nspr/work/nspr-4.9.2/mozilla/nsprpub/pr/tests/nbconn.c:368 # gdb ./nbconn nbconn.core GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
