Just received a customer complaint of a new crash. This is happening in a
recursive zip utility I wrote and appears to be getting triggered on this line:
dim zi as new ZipFileInfoMBS
[...]
zi.ExternalFileAttributes = flags
zi.DosDate = 0
z.CreateFile(relativePath +
fSrc.name,zi,"","",fSrc.CommentMBS,z.MethodDeflated,
z.CompressionBestCompression) // CRASH
Using MBS 10.1 under RB 2010R1 / carbon build.
Looks to me like CommentMBS is calling out to AppleEvents and that's crashing?
Perhaps this is something that used to be OK in a thread, but is no longer
thread-safe under 10.7?
