Siwymaligan Posted January 24, 2022 Report Posted January 24, 2022 Hi, I'm attaching logs after CTD during climbout from EDDN. Sim crashed shortly after setting FL190 after levelling off at FL70 during ERETO7K departure. FPLN loaded into FMS: EDDN ERET7K ERETO DCT KULOK L984 OKG DCT BALTU DCT LAGAR N871 OKENO Q277 AGAVA EPWA (No STAR selected during CTD). ACFT version is 1.1 as I wanted to wait with 1.2 to see if there aren't any issues with it. Best regards, Adam CL650_Log.txt Log.txt
Graeme_77 Posted January 25, 2022 Report Posted January 25, 2022 (edited) Report 2474 A frustrating situation. Feedback from the developer:This doesn't appear to be our fault, even though we tripped an internal assertion. The original assertion was: ...650[dr.c:137]: assertion "!__builtin_choose_exp... This basically means there's a NAN value being attempted to be written by our code. Tracing back through the math that produces this, the only way I can get this to trigger is if somebody wrote an infinity (div-by-zero) into one of these X-Plane datarefs: mach number, alpha angle or beta angle. Looking just 1 line above this assertion failure, I can see: E/FMOD: ... FMOD error 29 - Value passed in was a NaN, Inf or denormalized float. So something was scribbling bad information into datarefs. This most likely originated in a div-by-zero inside of X-Plane itself, as none of the datarefs are writable by plugins. I've added additional hardening against reading/writing infinities to datarefs, but all that will do this is crash sooner if X-Plane's physics fails like this. The only proper fix this is to find the flaw in X-Plane itself. Thread closed. Please submit any new crashes with a full log.txt file as a new thread to allow tracking. Thanks for your co-operation.
