Bug ID: 60516
Summary: cc1plus crashes compiling a method with a huge struct
as argument
Product: gcc
Version: 4.8.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: zaskar_84 at yahoo dot com.ar
cc1plus crashes when trying to compile a class method that receives a very big
argument (a 65kb struct) in Windows (reproducible with mingw32, no problems on
linux versions). I know that we are not supposed to make so big static
variables, but the compiler should compile and let the resulting program crash
or complaint about that instead of crashing itself. Here's the minimal code
that generates the error:
struct huge {
char c[256][256];
};
class Bar {
void foo(huge x);
};
void Bar::foo (huge x) {
}
I've noted that there's no problem if the method is implemented inline.
And here are versions and compiler output

No, it is fed completely valid insn, but just the note creation hasn't been
adjusted for the r163679 change.

With an improved C testcase actually with r163679.

Thanks for the patch. I am about to do a full-regression test for it. This
will take some time.
Quick test has shown that issue isn't 'thiscall' specific at all. stdcall, and
fastcall calling-convention do have the same issues. So I would suggest to add
these two testcases to the patch, too.

Did regression-test for 32-bit mingw for C, C++, and Fortran. No new
regressions occurred.
So patch is from my POV ok for trunk and branches
