I run a script that imports a few thousand records into the database. The script runs once for each of several XML files. What it does is parse the XML and for each element of a certain type creates a record in a rails database that gets indexed with acts_as_ferret. This worked fine before but today after a few files (70000 records) this started to happen for any file I tried:

...When the condition described above occurs, a 32-bit local variable, which is set to 65536 for large input buffers, is assigned to a 16-bit local variable, effectively causing it to be set to 0. Due to specific malloc(0) behavior, memory allocation routine will be passed, creating buffer of size (malloc_usable_size) 12. Next: for (i = HASH(c) & (n - 1); h[i] != HASH_UNUSED; We can see n-1 here, and n is equal to 0. Because i is an unsigned 32-bit integer, it would cause integer overflow. This code will be equal to i = HASH(c) & 0xffffffff. Binary AND operator reduces this to i = HASH(...

I have a new problem: Register RBP is used in a function foo. (I am not allocating RBP to any virtual register, the instances of RBP in function foo are in the machine code when my register allocator starts.) Function foo calls function bar. Register RBP is not saved across the call, though it is live after the call. Function bar includes a virtual register. The code that I'm using to
