#110 Saving a file with syntax errors can cause out-of-bounds exception in Dev-C++

[SilverNexus]

I was using Dev-C++ 5.6.1 TDM-GCC Portable. I accidentally had some bizarre syntax in my file ("free_faction_music(struct faction_music &freeMyContents){" was "free_faction_music(){struct faction_music &freeMyContents"). When I saved, it brought up an error box for me to send an error report, which I did twice. Both of those, however, occurred before I realized that I had made the syntax error shown above. I attached a screenshot of the error window, so I don't ruin some of the information in transfer.

It also had this stack trace in the error log:

Version: 5.6.1
OS Version: Windows 7 Professional 64-bit (build 7600)
Steps to reproduce:
This function causes it, it does not appear to matter where in the file it is placed:

void free_faction_music(){struct faction_music &freeMyContents){
if (freeMyContents.playing)
free_song_list(freeMyContents.playing);
if (freeMyContents.victory)
free_song_list(freeMyContents.victory);
if (freeMyContents.defeat)
free_song_list(freeMyContents.defeat);
}

Trying the same syntax problem on other functions in the same file did not reproduce the issue. It may have something to do with the variable declared with the "&" (since this is written in C, I'm not 100% sure that is valid, which may contribute to the error the program encounters).

Fixed as of 5.6.2. Thank you for reporting.
