Re: [Iodbc-bugs] Invalid connection string causes malloc errors

[Bo A. <boe...@ao...>]

Interestingly, I do not get this issue if I build iODBC myself. It only seems to happen with the prebuilt framework from iodbc.org.

Subject: Invalid connection string causes malloc errors




It seems that entering invalid connection causes iODBC to throw malloc errors. I haven't done an extensive test to see what version the problem started but it did work in 03.52.0709.0909 (the older version I had installed). Is this reproducible on your end?   
   
   
   
    
    $ /Library/Application\ Support/iODBC/bin/iodbctest   
    
    iODBC Demonstration program   
    
    This program shows an interactive SQL processor   
    
    Driver Manager: 03.52.1015.0210   
    
    
    
    
    Enter ODBC connect string (? shows list): =   
    
    iodbctest(86869,0xa11bc1d4) malloc: *** error for object 0x20: pointer being freed was not allocated   
    
    *** set a breakpoint in malloc_error_break to debug   
    
    iodbctest(86869,0xa11bc1d4) malloc: *** error for object 0x931e2827: pointer being freed was not allocated

    Have a nice day.
