Different results, Debug vs. Release

[PhilG57]

Why would a program run to conclusion when called via Pelles Project->Execute xxx, but crashes repeatedly when called via Project->Debug xxx?  This is with the same executable which was compiled under Debug.

Also, if during a Debug session (before it blows up), I can utilize the debugger to show 'Auto', 'Watch",  'Locals', and 'Registers', but when I click on 'Globals', the program and the Pelles environment immediately crashes.

Admittedly this is a large multi-project workspace effort, with lots of individual modules which are all old and ugly. But the difference in behavior between Debug and Release is perplexing and the crashing trying to check out Globals is downright frustrating.

Thanks in advance.
