[Freewx-maint] Bug#702378: libwxgtk2.8-0: segv printing postscript in a latin-1 locale

[Kevin Ryde]

Package: libwxgtk2.8-0
Version: 2.8.12.1-12
Severity: normal

Attempting to print to a postscript file in a latin-1 locale gets a
segfault.  For example the demo in
/usr/share/doc/wx2.8-examples/examples/samples/printing/

    File/Print menu
    click on the Print to File
    click ok
    enter a filename and directory
    click save
    =>
    segfault

gdb claims it to be in wxPostScriptDC::DoGetTextExtent() dcpsg.cpp line
2151 and has p==NULL.  If my sources are up-to-date that line would be

    for(p=(unsigned char *)wxMBSTRINGCAST strbuf; *p; p++)

Maybe it's something locale related.  If I make a utf8 and switch to it
like LC_ALL=en_US.UTF-8 then the print works.  In that case it warns too
that I don't have file /usr/share/wx/gs_afm/Helv.afm, if that makes a
difference.

Is that p strbuf thing a conversion to a locale string to measure the
characters or something?  Dunno what it should do if the locale is not
enough for the string to be printed, but you'd hope it didn't crash.
