<amz3`>héllo all :)

<lloda`>wingo: I've bisected the format bug above, http://paste.lisp.org/display/330766 to 723efdfc44695dbc816ede8373b5cab4951ad3b2, 'Fabricated expression tweak in CSE' in master. It's one line.

***lloda` is now known as lloda

<wingo>lloda: cool!!

<wingo>and strange :)

<wingo>lloda: feel free to push a revert if that's the right thing for you. i would like to fix it but i don't have a lot of cycles right now

<lloda>np, I'll push the revert then

<lloda>I take that back, I was missing one bisect step

<lloda>the bad commit is 0f2f5949a21572fad8355473200c7adc6d74f882 'Better unboxing' which is over my head :-/

<lloda>I'll mail bug-guile

<mvdw>How would I go about referencing a expression before evaluating it, say I want to pass (+ 5 3) to a function, but not evaluate it.

<lloda>(lambda () (+ 5 3)) ?

<mvdw>lloda: Yes, thank you.

<mvdw>I should've thought of that.

<lloda>yw

<dsmith-work>Wednesday Greetings, Guilers

<dsmith-work>wingo: # first bad commit: [c957ec7ab0f0a028910dc737e12191f7bdc1ca93] Use atomics for async interrupts

<wingo>dsmith-work: what platform?

<wingo>can you ulimit -c unlimited and get a "thr apply all bt" on the cores?

<wingo>s/cores/core file/

<dsmith-work>wingo: amd64

<wingo>compiler?

<dsmith-work>gcc (Debian 4.9.2-10) 4.9.2

<dsmith-work>Pretty much an up to date jessie system

<dsmith-work>So. I bisect seems to leave the workspace at the last good commit

<dsmith-work>s/I/So/

<dsmith-work>wingo: Ok, I have a core dump. What;s the proper gdb invocation?

<wingo>gdb libguile/.libs/guile core

<wingo>then thr apply all bt

<dsmith-work>Hmm. Doesn't seem very useful. There are no symbols

<dsmith-work>AhH! that's better

<dsmith-work>gdb libguile/.libs/lt-guile core

<dsmith-work>wingo: Want the whole thing to a list?

<dsmith-work>sneek: bugs?

<dsmith-work>sneek: botsnack

<dsmith-work>Aww

<wingo>dsmith-work: yes please :)

<dsmith-work>Afraid the mailer wrapped a bunch.
