Just the cause that the optimized dump looks differently, but is not wrong.
The bug happens during reload's register elimination.

The oracle correctly figures that c_1(D)->D.1593.a and c_1(D)->D.1597.c do not
alias. The problem is a general defect in FRE that causes us to never CSE
a load with the default definition of the virtual SSA name.

FYI, the testcase violates strict aliasing, so you should preferrably fix your
code or at least compile with -fno-strict-aliasing.
That said, GCC shouldn't crash on it.

I think this patch will not handle:
int main(void)
{
try {
}catch (int &a)
{
a = 1;
}
}
-- CUT ---
In fact exception_defines.h's defines does not handle them correctly anyways.
I am working on a patch

Also my -fignore-exceptions calls __built_trap for a throw and make sure that
throw with an expression that the expression is evaluated.

GNU assembler supports both
popcntl %edx, %eax
popcnt %edx, %eax
I guess we can just generate
popcnt %edx, %eax
The same goes for
popcnt %cx,%bx
popcnt %rcx,%rbx
popcntw

We do already know which x86 memory barrier instruction we need, that's not the
problem, no need to give us pointers to documentations. The problem is that
we'd like to not use explicit x86 instructions but

The PENDING= specifier needs to be a pointer to integer. It is used to assign
a logical value of TRUE or FALse to the variable given value.
Thus:
LOGICAL :: alogicalvalue
INQUIRE(10,pending = alogicalvalue)

I think this is then a dup of 37754. Janne is working some ideas and these are
similar to my thoughts. This fix here is in a high bug domain so we think we
should hold for 4.5, get it resolved and tested, then p

this code from the glib-2.18.2 testsuite segfaults during execution when
compiled with >= -O1 (not -O0 or -Os). i hope this is the information you
need. let me know if you need more.
