I basically assumed there was some reason I wasn't aware of for putting it in the .rsrc section, so focused more on trying to figure out how to get binutils to clear the readonly section flag. When I couldn't figure that out, I figured I'd ask here both about the "institutional knowledge" if there was a known reason why it needed to be in the .rsrc section and because I figured some people knowledgable in binutils pe stuff might also read this and be able to give me another idea on making the .rsrc section read/write again if it did need to stay in that section. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

Thank you! Not sure I'll follow up on this, ARM64 assembler still puzzles me. However, this way I can at least take a look.

Have a look at https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-nsswitch for the settings. By default account enumeration only returns the bare minimum for speed. Btw, there *is* a bug in that code, but it affects only domain menber machines, afaics.

Re: Cygwin installer hangs when running post-install scripts
Hi Corinna, I just updated https://gist.github.com/kevinushey/cdbd15cdf22e5cdcd094b0ad80347dce with that output (windbg-output-2.txt); let me know if that gives you what you need. As an aside, a new version of the Windows Insider edition was just released, and the memory addresses for the stubs in ntdll.dll have changed such that the original issue no longer occurs (ie, 0xe8 no longer happens to be part of the jumped-to address in the following stub), but I presume that is just luck and not an intentional change.

Thanks for the bug report. Fixed in git. The test release
cygwin-3.6.0-0.46.g70653fd8f1db containing this patch will be
available shortly.

BUG: gettimeofday() didn't handle first argument being NULL
this code works on Linux, but not msys2:
#include
#include
int main() {
struct timezone tz;
puts("a");
gettimeofday(NULL, &tz);
puts("b");
}
I guess the reason would be
winsup/cygwin/times.cc
extern "C" int
gettimeofday (struct timeval *__restrict tv, void *__restrict tzvp)
{
struct timezone *tz = (struct timezone *) tzvp;
static bool tzflag;
LONGLONG now = get_clock (CLOCK_REALTIME)->usecs ();
tv->tv_sec = now / USPERSEC;
tv->tv_usec = now % USPERSEC;
If so, the fix should be add if (tv != NULL)
I found this issue due to

As you know we got rid of this way to define the cygheap, but _cygheap_start was just defined this way so it's the address marking the start address of the cygheap. It was just the way it was. It's probably just as well to move _SYM (_cygheap_start) = .; to the begining of the .cygheap section. Did you try?
