Bug#973124: unison-2.48: FTBFS: ocamlc: OCaml has been configured with -force-safe-string: -unsafe-string is not available.
Source: unison-2.48
Version: 2.48.4-8
Severity: serious
Justification: FTBFS on amd64
Tags: bullseye sid ftbfs
Usertags: ftbfs-20201027 ftbfs-bullseye
Hi,
During a rebuild of all packages in sid, your package failed to build
on amd64.
Relevant part (hopefully):

> ./mkProjectInfo > Makefile.ProjectInfo
> UISTYLE = text

> Usage: ocamlc <options> <files>
> Options are:
> -a Build a library
> -alert <list> Enable or disable alerts according to <list>:
> +<alertname> enable alert <alertname>
> -<alertname> disable alert <alertname>
> ++<alertname> treat <alertname> as fatal error
> --<alertname> treat <alertname> as non-fatal
> @<alertname> enable <alertname> and treat it as fatal error
> <alertname> can be 'all' to refer to all alert names
> -absname Show absolute filenames in error messages
> -annot (deprecated) Save information in <filename>.annot
> -bin-annot Save typedtree in <filename>.cmt
> -c Compile only (do not link)
> -cc <command> Use <command> as the C compiler and linker
> -cclib <opt> Pass option <opt> to the C linker
> -ccopt <opt> Pass option <opt> to the C compiler and linker
> -color {auto|always|never} Enable or disable colors in compiler messages
> The following settings are supported:
> auto use heuristics to enable colors only if supported
> always enable colors
> never disable colors
> The default setting is 'auto', and the current heuristic
> checks that the TERM environment variable exists and is
> not empty or "dumb", and that isatty(stderr) holds.
> If the option is not specified, these setting can alternatively
> be set through the OCAML_COLOR environment variable.
> -error-style {contextual|short} Control the way error messages and warnings are printed
> The following settings are supported:
> short only print the error and its location
> contextual like "short", but also display the source code
> snippet corresponding to the location of the error
> The default setting is 'contextual'.
> If the option is not specified, these setting can alternatively
> be set through the OCAML_ERROR_STYLE environment variable.
> -compat-32 Check that generated bytecode can run on 32-bit platforms
> -config Print configuration values and exit
> -config-var Print the value of a configuration variable, a newline, and exit
> (print nothing and exit with error value if the variable does not exist)
> -custom Link in custom mode
> -dllib <lib> Use the dynamically-loaded library <lib>
> -dllpath <dir> Add <dir> to the run-time search path for shared libraries
> -dtypes (deprecated) same as -annot
> -for-pack <ident> Generate code that can later be `packed' with

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
