[Lazarus] Interesting issue when running programs

[Matt Shaffer]

And one more backtrace, after I discovered -Xs was being forced upon
compiled programs, removing symbols.

Starting program: C:\Users\Matt\Documents\TestCase/project1.exe

Program received signal SIGSEGV, Segmentation fault.
0x100177b7 in U_SYSINITPAS_ENTRYINFORMATION ()
(gdb) backtrace

(gdb) q

So yeah, it dies really early into execution. I'm just going to reinstall
Lazarus, as this seems like the best option for me.

(Although I still am curious as to why an app segfaults when being debugged,
but not when run without a debugger attached...)
