[v31.01.16] Crashes after certain syntax

[Alpengreis]

I entered following incorrect (no valid syntax) try:

for /l %n in (1,1,10) (for %fn in (*) if not isfile "tests3\%@format[[04,%n]\%fn]]" echo "%fn")

This will crash TC reproducable (here). TC restarts automatically after.

Even if the syntax is wrong, TC should not crash, so that seems a bug somewhere ...

Greetings

The Microsoft RTL is detecting the bad syntax and calling TerminateProcess.

The only way for me to work around that is to rewrite that part of the RTL (which will be a bit of a mess because it affects a lot of the string class).

Out of curiosity, what is wrong with his syntax, and how should he fix it?

@rconn

That's a difficult one then to fix ... I just thought I'll report it, because such crashes are never "nice".

Of course you decide to fix it or not.

However: thank you for letting me know!

His syntax is passing %[04s" as the format string, which is meaningless. The Format method in the RTL doesn't like it, and calls TerminateProcess.
