Re: [Boost-users] null instruction ptr bugcheck in regexp
I havn't received replies on this, and wonder where is the correct place that I should post this kind question. I got full stack using VS 2005. It tells that register EBP is corrupted in the function boost::re_detail::abstract_protected_call::execute. Before this function, the value of EBP value is correct. Is there any similar problem that has been known already? Thank you. Heidi On Fri, Jul 24, 2009 at 3:52 PM, Heidi Zhou <heidi_zhou@yahoo.com> wrote:
Hello! I am using boost regexp to do string/expression match. I got several dump files that have the same call stack when the crash happends. What my code does is copying user buffer (containing string to be mached) to an internal allocated buffer and then call boost regexp functions.
From the following result of windbg's "analyze", can you tell what cause the null intrstrucation ptr? I check the memory that contains the string to macht and didn't find any wrong. Also, btw, where can I find boost pdb? Thank you. ==================================================== FAULTING_IP: +0 00000000 ?? ???
