Hi. I'm writing a sort of "compiler" for a language similar to php (so it is not a compiler since it doesn't produce any object code, it only checks syntax and so on). I use delphi 6 on win32, and freepascal 1.9.x on Linux/i386 and Mac OS X. Sometimes I compile it with fpc under win32 too. It works great when compiled with fpc 1.9.0, but I have strange problems when using fpc 1.9.2 and 1.9.3: it compiles correctly, but I have a lot of acces violations when running the program, and the program behaves differently when compiled with or without range checking. This program makes an heavy use of dynamic arrays and recursion. I tried to debug it using gdb, and I noticed a bad behavoir in setlength function: I have a method that adds things to a dynamic array, using setlength to increase its size dinamically. When the array is empty, everything is okay (array grows to 1, and data is set). When I add another item, array grows to 2, but contents of the first element (element 0) are corrupted: when I try to access it, sometimes i receive garbage data, sometimes I have an access violation. I have this same problem under win32, linux/i386 and MacOS X.
I wasn't able to reproduce the bug in a simple program, so I would like to step into setlength to see what does happen. So, how can I compile a "debug version" of rtl so that I can use it when debugging the program?
