Re: [Tinycc-devel] TCC crashes on invalid structure reference

[Mike]

Its strange that you got that strange error, and I got
"[Program Error--title] tcc.exe has generated errors and will be closed 
by Windows.  You will need to restart the program.  An error log is 
being created.  [OK--button]".  This is the generic program crash window.

Ok, here are more specifics on my computer (to recreate the solution). 
I have Windows 2000, SP4 plus other patches.  I download and unpack 
"tcc-0.9.23.zip".  Then I take the EXEs from the TCC folder and put them 
into the root of the "tcc-0.9.23" folder, so that TCC.EXE can find 
INCLUDE, LIB, etc..  I put crash.c into "tcc-0.9.23", then create a 
command window, CD to "tcc-0.9.23".  Then, finally run "tcc crash.c" and 
I get the generic program crash window.

After looking in the event log, I find nothing added.
