minimal example with --save-tems
Run with: g++ -std=c++14 tls-error.cpp tls-main.cpp -o tls-error
d
This is a minimal example. The extra header / cpp unit is necesary and
compiling all in one compilation unit does not trigger this error.
Using -std=c++11 does not change the behaviour.
Running the command above yields no executable file and the following output:
/tmp/ccyxWUc5.o: In function `TLS wrapper function for A::var':
tls-main.cpp:(.text._ZTWN1A3varE[_ZTWN1A3varE]+0x5): undefined reference to
`TLS init function for A::var'
