>Description:
I ran into a problem when I tried to update www/firefox. Building
the port succeeded, but it failed during the install phase.

I duplicated the runtime environment and ran xpcshell on its own to debug
the problem and found that it core dumped.

Illegal instruction (core dumped)
I got this stack backtrace in gdb:

I then single-stepped through the code and found that it was trying to
execute an illegal instruction:
x8965ade0 in mozilla::services::_external_GetHistoryService ()
from
/usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd11.0/dist/bin//libxul.so

from
/usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd11.0/dist/bin//libxul.so
(gdb)
0x8833308d in XRE_GetBinaryPath ()
from
/usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd11.0/dist/bin//libxul.so
(gdb)
Program received signal SIGILL, Illegal instruction.
0x8833308d in XRE_GetBinaryPath ()
from
/usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd11.0/dist/bin//libxul.so
(gdb)
The fact that the problem is an actual illegal instruction and not a jump
to nonsense is confirmed by disassembling the code:
If I disassemble the offending bit of code, I see this:
0x88333083 <XRE_GetBinaryPath+195>: mov %ecx,(%eax)
0x88333085 <XRE_GetBinaryPath+197>: mov (%ecx),%eax

0x88333091 <XRE_GetBinaryPath+209>: mov %esp,%ebp

Compilation the file results in a lot of warnings:

I then compiled the offending source file to assembly language using
the all the same command line flags. The presence of the illegal
instruction is confirmed. Here is the offending function:
If I compile the file to assembler, this is what I see for

The this is not the only function in this file with the problem. There
are a total of 14 ud2 instructions in the assembly code output.
>How-To-Repeat:
Attempt to build and install www/firefox on i386 with clang 3.4.
Then recompile nsAppRunner.cpp in the
/usr/ports/www/firefox/work/mozilla-release/obj-i386-portbld-freebsd11.0
directory with the command line abovel, but just generate assembly
language output. Look for ud2 instructions in the output.
I've attempted to generate a smaller test case, but haven't had success so
far.
