Running the cygwin64 installer it seems to show up in the post extraction scripts: running: C:\cygwin64\bin\dash.exe "/etc/postinstall/0p_000_autorebase.dash" abnormal exit: exit code=2816 ... https://gitlab.winehq.org/bernhardu/wine/-/jobs/219836/viewer#L593 A +seh,+module run shows these addresses: mapping PE file L"\\??\\C:\\cygwin64\\bin\\cygwin1.dll" at 0x6ffffc360000-0x6ffffc693000 ... code=c0000005 (EXCEPTION_ACCESS_VIOLATION) flags=0 addr=00006FFFFC4AC045 info[0]=0000000000000000 info[1]=FFFFFFFFFFFFFFFF rip=00006ffffc4ac045 rsp=00000007ffffb688 rbp=00000007ffffc0e0 eflags=00010212 rax=00000000000002e7 rbx=00000000000009d0 rcx=00000000ffffffff rdx=0000000000000000 rsi=0000000000000000 rdi=00000007ffffc040 r8=0000000000000000 r9=0000000000000000 r10=0000000800000000 r11=00006ffffc4abfc7 r12=000000010041cce4 r13=00000007ffffc138 r14=0000000000000001 r15=0000000000000000 mxcsr=00001f80 cs=0033 ss=002b https://gitlab.winehq.org/bernhardu/wine/-/jobs/219836/viewer#L6144 https://gitlab.winehq.org/bernhardu/wine/-/jobs/219836/viewer#L7291 In a local debugger with a similar cygwin installation and the package cygwin-debuginfo installed, this address points to the xsave64 instruction: wine 'c:\cygwin64\bin\bash.exe' --login -i $ gdb -q --args dash (gdb) starti (gdb) pipe info share | grep cygwin 0x00006ffffb7b1000 0x00006ffffbae1408 Yes /usr/bin/cygwin1.dll (gdb) b * (0x00006ffffb7b1000 - 0x1000) + (0x00006FFFFC4AC045 - 0x6ffffc360000) Breakpoint 1 at 0x6ffffb8fc045: file sigfe.s, line 134.
