so it's yelled by the controlling shell. Try either/both

$ (crm -t -T -w ...) 2>&1 |grep -1000 'Floating.*exception' > log.txt

$ (strace -ifF crm -t -T -w ...) 2>&1 |\
$	grep -1000 'Floating.*exception' > log.txt

also, if you dare enough, try to run it in the gdb (w/out -t -T)

$ gdb --args crm -w ...

hopely it'd stops at the exception, at which point you'd issue 'bt' command
in gdb, to get the back trace to post here. Note that the crm binary to run
here shouldn't be the installed one, but the un-stripped one you get in src/
after compiling (rather bigger than /usr/local/crm114/bin/crm114), if you
compile from source, of course.
