I have posted a similar query earlier, but did not get a response. So posting it again.
Our client is facing crash on XMLScanner::CommonInit() while reading a null location. w3wp__DefaultAppPool__PID__5020__Date__09_16_2014__Time_05_15_30AM__982__Second_Chance_Exception_C0000005.dmp the assembly instruction at xerces_c_3_1+82d6a in C:\Program Files (x86)\<path>\IIS7\bin\xerces-c_3_1.dll from Apache Software Foundation has caused an access violation exception (0xC0000005) when trying to read from memory location 0x00000000 on thread 5. They are running 64 bit binaries on Windows Server 2008 64 bit. Is it an issue they have installed the product on Program Files (x86) and not on Program Files? The issue happens while IIS process restarts and occurs randomly only. We have done necessary changes as outlined in FAQs http://xerces.apache.org/xerces-c/faq-parse-3.html#faq-6 to make Xerces thread safe. Still the crash happens.
