------- Additional Comments From hartmut.birr at gmx.de  2005-30-08 23:35 -------
Rev 17596 to 17598 cannot solve the problem. Each mingw compiled binary does 
register its own exception handler. The mingw exception handler is defined in 
crt1.c. For the exception with the code EXCEPTION_ACCESS_VIOLATION, the mingw 
exception handler calls signal(SIGSEGV, SIG_DFL) and checks only for the 
result codes SIG_IGN and SIG_DFL but not for SIG_ERR. Each result code, except 
SIG_IGN and SIG_DFL, is interpreted as handler and called immediately. This 
results in the page fault at addresss 0xffffffff, because SIG_ERR is -1. Rev 
17596 to 17598 does only fix the wrong result code SIG_ERR. There was a reason 
for invoking the global exception handler. This reason is not solved with rev 
17596 to 17598.
