I am using thin as development web server with Rails on Debian 7. Since I've updated Rails to 4.2.7.1 I cannot launch thin anymore and I'm getting this error message : 

Using rack adapter
libgcc_s.so.1 must be installed for pthread_cancel to work
Aborted

I have a libgcc_s.so.1 file in my /lib/i386-linux-gnu/ folder but somehow thin cannot seems to find it there.

I have tried every answer to this question but it didn't help.

EDIT: I think the problem is related to the libv8 gem, that is a dependency to my project. The error shows when the default 5.3.332.38.1 x86-linux version of the gem is used. But if I force it to version 5.0.71.48.3 x86-linux, the error disappears.

You need to install the library for the right architecture:

apt search libgcc1

E.g. Try installing apt install libgcc1-amd64-cross (or libgcc1-x32-cross).

In /lib/i386-linux-gnu you've libraries for i386 binaries, so most likely you're missing libgcc1 for x86_64.

$ dpkg -S /lib/x86_64-linux-gnu/libgcc_s.so.1
libgcc1:amd64: /lib/x86_64-linux-gnu/libgcc_s.so.1
$ dpkg -L libgcc1:amd64
/lib/x86_64-linux-gnu/libgcc_s.so.1
