llvm dev - Nov 2011 - [LLVMdev] LLVM native code and GDB -> Segmentation Fault

Hi Duncan,
it is my program that dies.

Moreover, if I run ./program.native, it works.

You are missing something?

try running it under valgrind.

But the error is related to a conversion between llvm and gcc in
"gcc-program.s -o program"?
I need to use GDB to make an extraction of the information generated by GDB.

For other programs, the process that wrote the first post worked perfectly,
except for some.
That this is the problem, for the compilation is the need to inform the -lm
to link math libraries. It could be related to this -lm argument ?
