The CYGWIN_GUARD define in dcrt0.cc does not work on WIN98 where PAGE_GUARD is not available. Normally this does not occur but i ran into this when i forked in a thread other than the man thread. I got: T:\FORK\FORK.EXE: *** fork: couldn't allocate new stack guard page 0x112ADFFF, Win32 error 87 1334 [unknown (0xFFFA6E1F)] fork 388757 sync_with_child: child -186165(0x11C) died before initialization with status code 0x1 1609 [unknown (0xFFFA6E1F)] fork 388757 sync_with_child: *** child state waiting for longjmp with this test program: #include <pthread.h> static void * TestThread( void * ); int main(void) { pthread_t t; pthread_create(&t, NULL, TestThread, NULL); pthread_join(t, NULL); return 0; } static void * TestThread( void *not_used ) { switch (fork()) { case -1: return NULL; case 0: break; default: wait (NULL); } return NULL; } I have attached a small patch. 2002-08-15 Thomas Pfaff <tpfaff@gmx.net> * dcrt0.cc: Modified define for CYGWIN_GUARD (alloc_stack_hard_way): Fixed arguments for VirtualAlloc call.
