I'll try to whip up a minimal test case. Fixing shouldn't be too hard (though it is a bit annoying; ideally this should be both noreturn and void).

Re: [ANN] CHICKEN 5.2.0 release candidate available
Hi. The RC1 generates uncompilable C code for my Scheme code. This code worked for all previous Chicken versions (tested today: 5.1.0). If I use csc -O3 (-O2 is ok), I get 19 gcc errors, e.g. nallch.c:1395027: error: void value not ignored as it ought to be av2[3]=C_rest_arg_out_of_bounds_error(C_fix(0),C_fix(0),C_fix(0)); If I increase the optimization level to csc -O5, the error changes because this function call is inlined in the argument position of another function call, e g. 'gcc-8' 'nallch.c' -o 'nallch.o' -c -fno-strict-aliasing -fwrapv -DHAVE_CHICKEN_CONFIG_H -DC_ENABLE_PTABLES -O1 -march=nehalem -I/usr/local/chicken-5.2.0-64/include/chicken nallch.c: In function f_574889 nallch.c:924744: error: invalid use of void expression f_606388(t2,lf[908],C_rest_arg_out_of_bounds_error(C_fix(0),C_fix(0),C_fix(0)));} As other C problems in past weeks, it is related to the optimization of rest args. I like this optimization, but it seems to be more and more tricky ... Does anyone have a simple test case for such errors with rest args when compiling with -O3 or higher? Ciao Sven

[TFP'20] call for participation: Trends in Functional Programming 2020, 13-14 February, Krakow, Poland
- Call for participation 21st Symposium on Trends in Functional Programming tfp2020.org - The list of accepted papers is available at http://www.cse.chalmers.se/~rjmh/tfp/ The symposium on Trends in Functional Programming (TFP) is an international forum for researchers with interests in all aspects of functional programming, taking a broad view of current and future trends in the area. It aspires to be a lively environment for presenting the latest research results, and other contributions. * TFP is moving to new winter dates, to provide an FP forum in between the annual ICFP events. * TFP offers a supportive reviewing process designed to help less experienced authors succeed, with two rounds of review, both before and after the symposium itself. Authors have an opportunity to address reviewers' concerns before final decisions on publication in the proceedings. * TFP offers two "best paper" awards, the John McCarthy award for best paper, and the David Turner award for best student paper. * This year we are particularly excited to co-locate with Lambda Days in beautiful Krakow. Lambda Days is a vibrant developer conference with hundreds of attendees and a lively programme of talks on functional programming in practice. TFP will be held in the same venue, and participants will be able to session-hop between the two events. Important Dates --- Submission deadline for pre-symposium review: 15th November, 2019 -- passed -- Submission deadline for draft papers: 10th January, 2020 -- passed -- Registration (regular): 2nd February, 2020 Registration (late): 13th February, 2020 Symposium dates: 13-14th February, 2020 Visit tfp2020.org for more information.
