llvm dev - Nov 2011 - [LLVMdev] LLVM: segfault while modifying a thread-local global variable

Hi, guys.

Really strange situation: when I modify a thread-local GlobalVariable I get
a segfault. It seems to be a bug, doesn't it? Can u suggest me some
solution?

Thanks.

build LLVM with assertions enabled.  Then you may well get an assertion failure
with a helpful error message rather than an obscure crash.

Ciao, Duncan.

In my case the LLVM is built with assertions, but this doesn't help. From
your answer I conclude that thread-local globals are fully implemented in
x86 JIT. So this is strange...
