Well, a GUI application would produce a crash report. By default, a
command-line tool does not. You can change that using /Developer/
Applications/Utilities/CrashReporterPrefs.app.
Also, when you run a program using Instruments, its output goes to /
dev/console. You can check it using /Applications/Utilities/
Console.app.
I've tried attaching gdb to the process created by Object Allocations.
But it shows that executable ended normally.
Weird. I don't know why that would be happening.
I've also another question. I know how to set environment variables
when running executable from instruments. But how can I set them
when running from XCode and XCode-Debugger.
In the project window, find the Executables file group. (Where this
is depends on how you configured Xcode's interface.) Under that
group, find the executable of interest. Double-click it to open its
Info window. On the Arguments tab, you can provide command-line
arguments and environment variables.
Cheers,
Ken
