[Chicken-users] Optimizer bug

[Sven Hartrumpf]

Hi all.

Some months ago -optimize-level 2 stopped working for me.
As -optimize-level 1 still works, inlining must be the culprit (?):


/usr/local/bin/chicken nallch.scm -output-file nallch.c -debug-level 0 
-optimize-level 2

Warning: redefinition of standard binding: symbol->string

Error: shell command terminated with non-zero exit status 17920: 
/usr/local/bin/chicken nallch.scm -output-file nallch.c -debug-level 0 
-optimize-level 2


How can I track down this problem myself (i.e. find out
which expression causes the compiler error)?

(I want to make a minimal test case that I can share.)

Greetings
Sven
