Follow-up Comment #2, bug #30162 (project guile):
I came across the problem when I built Guile master on a Cygwin box with a
misconfigured iconv/libunistring that didn't have any encodings other than "C"
and "POSIX" available. With only those encodings, the guile-tools compilation
process on non-ASCII files appears to succeed but actually creates zero-length
.go files. When running Guile with zero-length .go files, there is some sort
of scm_misc_error about mmap'ing .go files. That error happens really early
in the startup, before a prompt has been created. This leads to the recursive
"abort to unknown prompt" problem, which causes segfault.
At first glance, it doesn't appear that this problem is related to today's
hydra build failure.
