Jim Wilson <wilson at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |wilson at gcc dot gnu.org --- Comment #2 from Jim Wilson <wilson at gcc dot gnu.org> --- I've reproduced this problem with a RISC-V gcc-8.x compiler, and tracked it down to the first patch for bug 81968, in comment #60. With the patch reverted, the testcase works. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81968#c60 The RISC-V testcase works with Linux hosted and Cygwin hosted toolchains, and only fails for mingw32 hosted toolchains. Maybe an LLP64 problem with the patch? I didn't see any obvious type error in the patch though. I had to borrow a windows machine from our IT group to look at this, and they have since taken the loaner back, so I don't have a machine at work I can use to debug this at present.
