I have tried a small test program with cpu unit and it works neither with dpmiexcp nor without dpmiexcp. I get with dpmiexcp and snapshot 2.05 (10.3.2007) following error:
SIGSEGV FPC General Protection Fault 2.05 without dpmiexcp An unhandled exception occured at EAccessViolation : Access Violation List of adresses..... ... It works with fpc 1.06(26.04.2002) and without dpmiexcp. It crashs with dpmiexcp. Error:SIGILL I can´t test the new compiler version for my "real program" because it doesn´t compile my sources with graphix unit. regards Dirk Florian Klaempfl schrieb: > Dirk Verwiebe schrieb: >> Hello Florian, >> >> exception handling was the problem.I have removed the dpmiexcp unit and >> now it works again. > > Well, this is only a workaround.
