if I delete the below "memcpySequence" in Compiler.xml
Will solve
Code:
Catched exception 'java.lang.NullPointerException' while compiling 0x08B15504 (0x08B151F0-0x08B15798)Code:

Interesting! Could you provide a compiler DEBUG log of the good case (i.e. with the memcpySequence entry deleted).
Thank you!

RE: memcpySequence native code bug - gid15 - 04-26-2014
Thank you!
I've tried to solve this case in a generic way with r3503. Could you generate a new compiler DEBUG log to check if the fix worked properly?
RE: memcpySequence native code bug - sum2012 - 04-26-2014
Good.Fixed.but I cannot seee log error.

RE: memcpySequence native code bug - gid15 - 04-27-2014
Thank you! I just wanted to check if the DEBUG log I added was displayed:
Code:
05:11:30 DEBUG compiler - ExtractorThread - 0x08B1541C: branching to the 2nd instruction of a native code sequence, assuming the 1st instruction
