It is reported that this change causes args_out_of_range
error in Faset of status_message if strsignal returns a
string encoded in some locale encoding.
2009-06-09 Dmitry Dzhus <address@hidden> (tiny change)
* process.c (status_message): Fix handling of multibyte signal
string (Bug#3499).
That is because:
string = build_string (signame);
returns a unibyte string containing 8-bit bytes in non-UTF-8
locale, and Faset can't change the multibuteness of string
in such a case.
So, I installed the attached patch. But, as I don't have a
system whose strsignal returns a localized string, I can't
test it. At least, I sent this patch to the above bug
reporter and he said that the patch surely fixed the
problem.
