Summary: __thread storage class variable gets optimized out on
ARM
Product: gcc
Version: 4.5.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c

test case source code
My host system is x86_64 and I am cross compiling this file(attached) for ARM
with following command: arm-unknown-linux-uclibcgnueabi-gcc -pipe -O1 -Wall
thread_test.c -o thread_test
Executing ./thread_test on my ARM system results in segfault. If I comment out
test_set() function or remove __thread specifier or compile it without
optimizations (-O0) test passes.
I tried this test also on my host system (Fedora 14) and it does not fail
there.
My cross compiler is vanila GCC + patches from:
http://git.buildroot.net/buildroot/tree/toolchain/gcc/4.5.1
It took me about a week to realize what is going on and make this test case out
of not working cross compiled pulseaudio-0.9.22 server :)
