==== Yet more memory mismanagement ==== | |||
When FG is trying to exit, it is very likely to abort | |||
with a message such as | |||
*** glibc detected *** double free or corruption (!prev): 0x0ad08b88 *** | |||
There are at least three different instances of this bug, | |||
each producing a different traceback. Here is one such | |||
traceback: | |||
