This is a catch-all bug report for miscompilations of machine-generated code that is generated by the Gambit-C Scheme->C compiler. Giovanni Bajo suggested that I at least document the problem with proper preprocessed files, etc. All 34 megabytes of the files are at http://www.math.purdue.edu/~lucier/GNATS/GNATS-16/gambit-test.tgz They were generated and the bug was verified with the following commands: [EMAIL PROTECTED] gambc40b11]$ env CC='gcc -g -save-temps' ./configure --enable-single-host [EMAIL PROTECTED] gambc40b11]$ gcc -v Reading specs from /home/lucier/local/bin/../lib/gcc/i686-pc-linux-gnu/4.0.0/specs Configured with: ../configure --prefix=/home/lucier/local/ --enable-languages=c --enable-checking=no Thread model: posix gcc version 4.0.0 20041118 (experimental) [EMAIL PROTECTED] gambc40b11]$ make <stuff removed> [EMAIL PROTECTED] gambc40b11]$ cd bench [EMAIL PROTECTED] bench]$ ./bench -c no gambit fib Testing fib under Gambit-C Compiling... ./bench: line 518: 25754 Segmentation fault LD_LIBRARY_PATH=../../../lib GAMBCDIR=../../../lib ../../../gsc/gsc -:=../../.. $1.scm gcc: fib.c: No such file or directory gcc: fib_.c: No such file or directory Command exited with non-zero status 1 0.00user 0.00system 0:00.01elapsed 0%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (153major+23minor)pagefaults 0swaps ls: fib: No such file or directory Running... time: cannot run ./fib: No such file or directory Command exited with non-zero status 127 0.00user 0.00system 0:00.00elapsed ?%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (24major+8minor)pagefaults 0swaps [EMAIL PROTECTED] bench]$ cd sys/gambit [EMAIL PROTECTED] gambit]$ ls fib.scm [EMAIL PROTECTED] gambit]$ env GAMBCDIR=../../../lib ../../../gsc/gsc -:=../../.. fib.scm Segmentation fault [EMAIL PROTECTED] gambit]$ env GAMBCDIR=../../../lib gdb ../../../gsc/gsc GNU gdb 6.3 Copyright 2004 Free Software Foundation, Inc.
