<div dir="ltr">Hi Bill:<div><br></div><div>Not sure if it was intentional, but the old builds set CC, CXX, and LD_LIBRARY_PATH explicitly, but the new ones don't.

I tried testing some earlier revisions on the new OS that had worked fine under the old but they generate the same errors now so it isn't any changes in llvm.<br>
<br>
There are two different errors:<br>
<br>
FATAL: ThreadSanitizer: unsupported VMA range<br>
FATAL: Found 47 - Supported 44 and 46<br>
<br>
and<br>
<br>
FATAL: Code 0x00010eddf660 is out of application range. Non-PIE build?<br>
FATAL: MemorySanitizer can not mmap the shadow memory.<br>
FATAL: Make sure to compile with -fPIE and to link with -pie.<br>
FATAL: Disabling ASLR is known to cause this error.<br>
FATAL: If running under GDB, try 'set disable-randomization off'.<br>
<br>
Obviously something changed when I updated the OS but I am not sure how to fix it. The compilation options didn't change and ASLR isn't disabled. I used the same gcc compiler to build llvm under the different OS releases.<br>
<br>
The first full test after the OS update is here: <a href="http://lab.llvm.org:8011/builders/sanitizer-ppc64le-linux/builds/3636" rel="noreferrer" target="_blank">http://lab.llvm.org:8011/build<wbr>ers/sanitizer-ppc64le-linux/<wbr>builds/3636</a><br>
<br>
Any ideas? Thanks!<br>

Here's the full output from one of the failures:<br>
