[Bug binutils/29006] New: alloc(): invalid size (unsorted) with -fstack-protector -lssp

[manisandro at gmail dot com]

https://sourceware.org/bugzilla/show_bug.cgi?id=29006

Bug ID: 29006
   Summary: alloc(): invalid size (unsorted) with
-fstack-protector -lssp
   Product: binutils
   Version: 2.38
Status: UNCONFIRMED
  Severity: normal
  Priority: P2
 Component: binutils
  Assignee: unassigned at sourceware dot org
  Reporter: manisandro at gmail dot com
  Target Milestone: ---

I'm trying to build mingw-llvm-1.14.0 [1] with
mingw-binutils-2.38-1.fc37.x86_64, mingw-gcc-12.0.1-1.fc37.x86_64.

[1] https://smani.fedorapeople.org/mingw-llvm-14.0.0-1.fc37.src.rpm

Linking llvm-cvtres.exe fails with 

malloc(): invalid size (unsorted)
collect2: fatal error: ld terminated with signal 6 [Aborted], core dumped
compilation terminated.

Reduced command line:

$ i686-w64-mingw32-g++ -fstack-protector -lssp -Wl,--whole-archive
CMakeFiles/llvm-cvtres.dir/objects.a -Wl,--no-whole-archive -o
../../bin/llvm-cvtres.exe @CMakeFiles/llvm-cvtres.dir/linklibs.rsp

Note: Error only appears if both -fstack-protector and -lssp are present.
Appears to be a regression since mingw-binutils-2.37-5.fc37.

Valgrind says:

$ valgrind i686-w64-mingw32-g++ -fstack-protector -lssp -Wl,--whole-archive

Hi Nick, sorry for the late reply, I missed your comment! Just applied to
mingw-binutils in Fedora and mingw-llvm is now building fine, thanks!

I suppose a similar fix/sanity check is also needed for
a->u.auxent.x_sym.x_tagndx.l: running

mingw-objcopy --only-keep-debug LLVM.dll LLVM.dll.debug

results in:

[Bug ld/28231] New: relocation truncated to fit: R_X86_64_32S against `.text'

[manisandro at gmail dot com]

https://sourceware.org/bugzilla/show_bug.cgi?id=28231

Bug ID: 28231
   Summary: relocation truncated to fit: R_X86_64_32S against
`.text'
   Product: binutils
   Version: 2.37
Status: UNCONFIRMED
  Severity: normal
  Priority: P2
 Component: ld
  Assignee: unassigned at sourceware dot org
  Reporter: manisandro at gmail dot com
  Target Milestone: ---

On a current Fedora Rawhide with 

mingw64-binutils-2.37-2.fc36.x86_64
mingw64-gcc-11.2.1-3.fc35.x86_64

The following

typedef struct __A {
} A;

int main(int argc, char** argv) {

A a;

__asm__ __volatile__ (
"leaq   1f, %%rax"  "\n\t"
"1:""\t"
:
/* No outputs */
:
[a] "m" (a)
:
"%rax"
);

return 1;
}


results in 

$ x86_64-w64-mingw32-gcc -o test test.c
/tmp/ccfMmoPi.o:test.c:(.text+0x18): relocation truncated to fit: R_X86_64_32S
against `.text'
collect2: error: ld returned 1 exit status

This is a reduced testcase from mingw-tk, which fails to build due to this. The
full code triggering this [1] asm block.

(Note: I don't know asm well enough to judge whether the asm code in the test
case is a valid test case, I just reduced the full code to the minimum lines
triggering the error. Filing this attemping to fix a FTBFS of mingw-tk)
