Bus error while compiling with gcc

Question

I can't seem to be able to compile even simple C programs anymore; I can't seem to be able to pinpoint what changed from yesterday, when all seemed to be fine.

I'm using gcc 5.2.1.

Compiling this program (or any other program)

#include <stdio.h> int main(int argc, char *argv[]) { printf("Hello world!\n"); return 0; }

gives me this error:

<built-in>: internal compiler error: Bus error Please submit a full bug report, with preprocessed source if appropriate. See <file:///usr/share/doc/gcc-5/README.Bugs> for instructions.

I'm at loss; what I found while searching on the internet are posts from a few years back detailing bugs that have been solved, or bus error generated from a C program for incorrect use of memory.

I've tried purging and reinstalling gcc with apt-get (I'm using Ubuntu), but nothing changed.

@fluter Already tried with apt-get, added an edit to the post — gcali

@sjsam I didn't change anything in gcc, at least not voluntarily; I experimented with some warning options (-Werror, -Wextra, -Wall and so on), but as far as I can see doing that should be of no consequence to gcc itself. I haven't updated my system since last week, so I shouldn't have upgraded gcc either. Again, voluntarily at least. — gcali

I would check the memory, file system, and disk surface, and maybe did other hardware checks as well.

fsck said everything was fine; I will try with a memtest as soon as I'm able to

I was having issues with my wireless, too; I have no idea how or why, but after entering the command

sudo apt-get install --reinstall bcmwl-kernel-source

and rebooting, gcc started working again. I'm confident that this did the trick, as I tried compiling just before issuing the command.

While I'd still like to understand why that happened, I guess this fixed the problem.

I have the same problem I could not install mysqldb and my GCC was giving error like that:

I fixed the problem in Ubuntu by updater and the Ubuntu partial version

The problem arises because of partial installation of other packages.

Steps:

1) got to updater
2) find there to update and restart Ubuntu
