@zkanda, can I ask for some clarification about your computer architecture? The gist says you're running this on an Intel Prescott.

According to Wikipedia, there are both 32-bit and 64-bit versions of the Prescott. Which one are you using? We unfortunately don't support 32-bit architectures at this time (but would welcome assistance if you'd like to help support it).

From GCC's web site:

‘prescott’
    Improved version of Intel Pentium 4 CPU with MMX, SSE, SSE2 and SSE3 instruction set support. 

Is that part of your CFLAGS variable or did Linuxbrew insert it itself?

Thanks a bunch!

By the way, I'll probably move this issue to Linuxbrew/brew if I determine that it's a bug in Linuxbrew itself and not just gdbm in particular.

Yes, this is not just about gdbm, everything that I need to compile is having this issue. This is running in VM in our server which is supposed to be 64-bit.

Here is the output of uname -a

→ uname -a
Linux dev-server 3.19.0-59-generic #65~14.04.1-Ubuntu SMP Tue Apr 19 18:57:09 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

I didn't change any CFLAGS settings as I don't even know how to do that but I would be willing to help on whatever I can.
