[Bug target/79935] DJGPP: misaligned stack in static constructors
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79935 Andris Pavenis changed: What|Removed |Added CC||andris.pavenis at iki dot fi --- Comment #6 from Andris Pavenis --- Failed to reproduce - gcc-6.3.0 - Windows 10 32 bit VM (VirtualBox) under Fedora 25 x86_64 - DJGPP libc trunk version (should also work with DJGPP v2.05) Alignments supported by GCC (up to 128 seems) to work OK for me.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79935 --- Comment #5 from DJ Delorie --- DJGPP issues should be sent to the dj...@delorie.com mailing list, or comp.os.msdos.djgpp newsgroup.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=79935 --- Comment #4 from jwjagersma at gmail dot com --- > More likely, DJGPP just doesn't support more than 8-byte alignment. I just had the same problem in a normal function too, so I suppose that is the case then. I do think djgpp should support 16-byte alignment since programs compiled with it could potentially use SSE instructions (which is what I'm trying to do, using -O3 -march=pentium3) which cause GP faults on misaligned memory access. Where do I submit this to the djgpp list? The bug tracker on delorie.com seems very inactive.

Either way, this is something that should be investigated on the djgpp list first, and brought back here only if it's proven to be a gcc problem.

There is e.g.: gcc/config/i386/cygming.h:#define STACK_REALIGN_DEFAULT TARGET_SSE gcc/config/i386/sol2.h:#define STACK_REALIGN_DEFAULT (TARGET_64BIT ? 0 : 1) But gcc/config/i386/djgpp.h doesn't override it.
