crash

问题 The Info I recently launched an app on the AppStore. After testing on the simulator thousands of times, and actual devices hundreds of times we finally released our app. The Problem Reviews started popping up about app crashes when the user launches the app. We figured that the app crashes on launch on iOS devices with less than (or equal to) 256 Mb of RAM . The following devices are devices our app supports with less than 256: iPod Touch 4G iPhone 3GS iPad 1 The app doesn't always crash.

问题 What should I (as a Java programmer who doesn't know anything about JVM internals) do when I come across a JVM crash? In particular, how would you produce a reproducible test case? What should I be searching for in Sun's (or IBM's) bug database? What information can I get from the log files produced (e.g. hs_err_pidXYZ.log )? 回答1: If the crashes occur only one one specific machine, run memtest. I've seen recurring JVM crashes only two times, and in both cases the culprit turned out to be a

问题 The following consistently crashes my R session. Tested on two machines, Ubuntu and Mac OS X with similar results on both. Brief Description: Calling write.table on a data.frame with factor column of all NA's. The original data set is rather large, and I've managed to isolate the offending column and then create a similar vector, named PROBLEM_DATA below, which causes the same crash. Interestingly, sometimes R crashes outright, othertimes it simply throws the following error: Error in write

问题 I'm calling a function from a DLL, like this: __declspec ( dllimport ) bool dll_function(...); int main() { [...] if (dll_function(...)) { [...] } } In some cases, the data I pass to the DLL function will lead to a crash of the DLL. Is it possible to catch this so my application doesn't crash as well (without modifying the DLL which is not created by me)? 回答1: You can catch AVs with the __try and __except keywords in the MSVC compiler. Not all that useful, you have no idea what kind of damage

问题 I tested an app that is currently working with the VFR-Reader-Core on iOS8 and I get a complete crash when I try to open a PDF from it. Am I the only one with this problem? any idea of where I can search to correct this? Here is the crash report Thank you 回答1: In iOS 8, Te file system layout of app containers has changed. Applications and their content are no longer stored in one root directory. From the iOS 8 Release Notes: The file system layout of app containers has changed on disk. Rather
