Extended Description

Hi,

llvm-dis runs out of 1Gb of memory on a 5Mb .bc file. Checking
it with massif and memcheck didn't produce anything interesting,
no obvious memory leaks, and the allocation is quite ballanced.

It seems like some cleanup is missing after each function is
disassembled.

Unfortunatelly, I can't upload the .bc file due to intellectual
property issues.

Without some way to reproduce/diagnose it, there is no way for us to fix this.

Sorry,

The behaviour seems to be caused by a recursive type that is so long that its
ASCII representation cannot be held in memory.
