Hi! Guile 3.0.4 is segfaulting when using https://github.com/aconchillo/guile-json (release 4.4.0, 89e2ce975064baf4f434de4d97e54aac704769a0) The bug has been fixed in guile-json, but according to the manual "When Guile crashes, it is a bug", so I'm reporting this here, too. The code that made guile crash is the following: #+begin_src scheme (use-modules (json)) (json-string->scm "[123e-10000000]") #+end_src It's either crashing at 0x00007ffff7bfea60 in __gmpn_copyi_core2 () from /gnu/store/35afkywncrr5xsb4cxcljf6rpjcb7f61-gmp-6.2.0/lib/libgmp.so.10 or 0x00007ffff7bfefbe in __gmpn_lshift_core2 () from /gnu/store/35afkywncrr5xsb4cxcljf6rpjcb7f61-gmp-6.2.0/lib/libgmp.so.10 I'm running guile on guix (#6135e55f5ce39c7947288d54de8727eb5aa0e43c). Thanks!
