This is because signal handling in windows console applications is rather different from unix apps. If control-c is hit on a console application Windows creates a new thread which executes the control-c signal handler. Now, if the SCM handler does the longjmp back to the repl loop it does it via the stack of the signal handler thread which results always ever is an access violation. The solution to this problem is to let the signal handler thread raise a software interrupt in the main thread. This is done with the following steps: 1. contol-c is hit 2. Windows creates the signal handler thread which in turn executes the routine win32_sigint as its signal handler. 3. The handler suspends the main thread and gets the main threads register context. 4. The handler simulates an interrupt call on the main thread by pointing Eip to the sigintstub stub function and also simulates a pushad , pushf of the main threads registers 5. The handler resumes the main thread which when scheduled will execute sigintstub, which in turn calls the proper signal interupt (scamble_signal) */ #ifdef _WIN32 /* POCKETCONSOLE has the signal handler implemented in the runtime */ # ifndef POCKETCONSOLE # define WINSIGNALS # endif #endif #include "scmflags.h" /* user specified, system independent flags */ /* IMPLINIT is the full pathname (surrounded by double quotes) of Init.scm, the Scheme initialization code.
