c++.wxwindows - out of memory error

Digital Mars C/C++ Compiler Version 8.42.5n

I have a program with about 8000 lines of code, and recently added a new 
member function


bool MyFrame::CopyTemplate (const wxString & sFile, const wxString & 
sDestName, const wxString & sTextToReplace)
{

     wxString sCode = sExeRoot + sCodeDir;
     sCode = sCode + wxFILE_SEP_PATH ;
// real code ommitted
     return FALSE;
}

If I comment out the 2 sCode lines all is well, but with them in I get 
the error message shown below. How can i debug the memory error?

Hi Chris,

Don't know, it sounds weird. But, have you tried the -HPxx compiler switch.
See here http://www.digitalmars.com/ctg/ctg.html

I think(?) the default is -HP30, for 30 MB memory pool.  I've had to use
about 90 MB in some of my builds.

A word of caution if you are using the IDDE (which it looks like you are
not). After setting the -HP switch in the IDDE, it looks like you actually
have to close and re-open the IDDE for the setting to take effect; at least I
did, and it caused a bit of headache.

thanks doug, this was a good fix. I didn't find a reference for the -HP 
fix in either the output of dmc or on the 
http://www.digitalmars.com/ctg/ctg.html web page

No problem. In the left pane, Tools->DMC, it is listed as a compiler switch
on the web page.

Cheers

It could be running out of memory because of a recursive expansion of a
template or function. Can you try to cut it down to a minimal program?
