...I found that the X86CompilationCallback_SSE wrapper for X86CompilationCallback2 is not setting up properly for the PIC invocation. Before you can correctly invoke a function via the Procedure Linkage Table (plt), the ABI mandates that ebx is pointing to the GOT (Global Offset Table) (see http://www.greyhat.ch/lab/downloads/pic.html) Dump of assembler code for function X86CompilationCallback_SSE: 0xb74544f8 <X86CompilationCallback_SSE+0>: push %ebp 0xb74544f9 <X86CompilationCallback_SSE+1>: mov %esp,%ebp 0xb74544fb <X86CompilationCallback_SSE+3>: push %eax 0xb7...

Hello, Corrado > Before you can correctly invoke a function via the Procedure Linkage > Table (plt), the ABI mandates that ebx is pointing to the GOT (Global > Offset Table) (see http://www.greyhat.ch/lab/downloads/pic.html) This is known issue, just nobody realized, that we have bunch of non- PIC-aware assembler code. :) Fixing would be not so trivial though, mostly due to ABI differences between linux / darwin / mingw. Please file a PR. Thanks! --- With best regards, Anton Korobeyniko...
