[Boost-users] null instruction ptr bugcheck in regexp

Subject: [Boost-users] null instruction ptr bugcheck in regexp

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.
