Capturing a stack trace from another thread while it is runng requires that you suspend it first, otherwise you may end up with a corrupt stack trace This can be done with the Th read c l a s s ' s S u s pend method, as we'll see later; after you are done capturing the trace, you must remem ber to resume it with the Res ume method Thread suspension is generally speaking a dangerous activity, so please first refer to and read the later section if you intend to do this

A stack overflow can happen in two situations: 1 A thread tries to commit more stack pages than it has reserved 2 Committing a new guard page fails due to lack of physical memory and / or pagefile space The former often happens due to application bugs, such as infinite recursion But it can occur due to deep callstacks, especially if the size of the

stack reservation is smaller than the default of 1 MB, as is the case with ASPNET and WSDLEXE Extensive use of stack allocations via C#'s st a c k a l l o c keyword, fixed arrays, large value types, or VC++'s _a l l o c a function can make overflows more likely A workaround for such situations is to increase the stack size of threads in the program, either by changing the source or by editing the PE file to have larger default stack sizes, as described earlier in this chapter But in most cases, a better solution is to treat it as a bug and rely less aggressively on stack allocation Running out of pagefile space happens only under extremely stressful (and, one hopes, rare) conditions, that is, when there's no free disk space on the machine to back stack memory in the pagefile Typically there is no way to deal with this programmatically, except to fail as gracefully as possible and perhaps notify the user so that he or she may respond by freeing up resources It is particularly important, albeit difficult, to ensure user data doesn't become corrupt in such situations This is often treated similar to out of memory in that it's notoriously difficult to harden libraries and pro grams to respond predictably in such situations Stack overflow is usually catastrophic for Windows programs Some Win32 libraries and commercial components may respond very poorly to it For example, a Win32 C R I T I CA L_S ECTION that has been initialized so as to never block can end up stack overflowing in the process of trying to acquire the lock Yet MSDN claims this cannot fail A stack overflow here can lead to an orphaned critical section at the very least, and can cause subsequent deadlocks Worse, the C R I T ICA L_S ECTION may even become corrupt in some circumstances This only happens in very low resource conditions, which are difficult to reproduce and test Because of the extreme difficulty associated with stack overflow hard ening, very little of the library code Microsoft ships, including Win32 and the NET Framework, can continue operating correctly after a stack over flow has occurred The core of the Windows as and the CLR itself are hard ened, but usually the only intelligent and conservative response to stack overflow is to terminate the process abruptly And that's just what the CLR does (as of 20) It reacts to stack overflow by issuing a fail fast (see E n v i ronment F a i l F a st ) This logs a Windows Event Log entry and immediately terminates the process without unwinding
