If you use XOAUTH2 to send or receive to/from Gmail's SMTP/POP3 servers using XAUTH2, this might affect you. There was a bug that could cause post(1) and inc(1) to crash if you have 4 or more accounts in your oauth-gmail file. I just committed a fix:
Fixed memory corruption in post(1) and inc(1) when using XOAUTH2. An internal table for the oauth entries was initially sized at 4, and then reallocated if the user has 4 or more. However, the reallocation didn't account for the size of the allocated structure. Also, increased the initial size to 16, trading off slightly increased memory usage for performance. David
