TCC vanishes

[Jim Cook]

I'm having a problem switching to local aliases and then modifying the alias
list.

TCC 11.00.37 Windows XP [Version 5.1.2600]
TCC Build 37 Windows XP Build 2600 Service Pack 3

I normally have Option / Local Aliases unchecked and use global aliases.

I clicked Start / Run / <path>TCC.EXE then typed:


D:\>*option //localaliases=yes

D:\>*alias z=foo

As soon as I press Enter, the TCC application vanishes. This also happens
when it is a tab within TCMD.


My hope was that by using option localaliases I could do some alias testing
without harming my global list.

Reproducible here, build 38, x86 and x64 versions. Unfortunately, in neither case a .GPF file is produced. Debugging in Visual Studio gives:

Not supported (and never has been). You can only change that from the
OPTION dialog.

To switch between global and local aliases on the fly, use the ALIAS /L
command. Use ALIAS /G to switch back.

How do we find out what is supported, and what isn't?

If it's not documented, it's not supported. LocalAliases is an undocumented
directive. (And there are two other documented ways to do the same thing.)
