Why the application reports "cannot allocate memeory in static TLS block" when using Tsan?

[ran...@gmail.com]

Hi everyone,

When i compiles dynamic library with -fsanitize=thread -fPIC -pie and links with  -fsanitize=thread -fPIC -ltsan, the generated application will report a error like "XXX/lib64/libtsan.so.0:cannot allocate memory in static TLS block".

gcc version : 5.3

glibc version:2.18

linux version: suse linux 2.6.32.12-0.7-default

Hi,

I don't remember ever seeing such error.

Searching internet "cannot allocate memory in static TLS block",
brings several suggestions:
2 suggest that adding -lpthread can fix the problem:

2 suggest bugs in glibc:

Generally, updating your software can help. E.g. 2.6.32 was released
long before we even started thinking about creating any of sanitizers.
We never tested on 2.6.32.
