Subject:Release works Debug (still) crashes on OS X Leopard, Xcode 3.0 (Part 1)
View as plain text  
This is driving me nuts.  The release build works like a champ, and  
the debug version crashes and burns.  (Same issue that I have been  
posting about).  I am also using the exact same mysql and mysql dylibs  
for both builds.

Do you guys see anything blatantly wrong below?  If you can spare a  
few minutes and look at the stuff below, to help me through this, I  
would be grateful, ugh...  I am curious if it's some little quirk with  
the debug build set up that I just haven't figured out.

Down below is the following:
1) gcc compiler switches for release mode (compiles, links, and runs  
fine)
2) gcc linker switches for release mode (compiles, links, and runs fine)
3) gcc compiler switches for debug mode (compiles, links, and crashes)
4) gcc linker switches for debug mode (compiles, links, and crashes)
5,6,7) Are in message part 2

Here is what is sent to gcc for the release builds:  (This works)
