Hi,
I have a program which calls a function which has an all-inclusive MySQL
set of code (i.e. MySQL is initialized, used, and released within the
span of the single function). The first time the function is called it
function properly, but on subsequent calls, the function terminates with
a segmentation violation. Can I not create and destroy MySQL structures
within the span of a single function and then call it over again? Here's
the full backtrace from gdb.
