Bug 20380 – std.net.curl: misbehaviour on arch 'arm32v7 gnueabihf' (Raspberry/Raspbian/Buster)

Tried to do this: ''' import std.net.curl; import std.stdio; void main() { auto data = get("https://acme-staging-v02.api.letsencrypt.org/directory"); writeln(data); } ''' Works fine on intel, but crashes on Raspberry: ``` pi@raspi4:~/builds $ ./curldownload-gdc std.net.curl.HTTPStatusException@/usr/lib/gcc/arm-linux-gnueabihf/8/include/d/std/net/curl.d(1050): HTTP request returned status code 0 () ---------------- 0xb6d29723 pure @safe bool std.exception.enforce!(bool).enforce(bool, lazy object.Throwable) ???:0 0x18fb3 char[] std.net.curl._basicHTTP!(char)._basicHTTP(const(char)[], const(void)[], std.net.curl.HTTP) /usr/lib/gcc/arm-linux-gnueabihf/8/include/d/std/net/curl.d:1050 0x16f63 char[] std.net.curl.get!(std.net.curl.HTTP, char).get(const(char)[], std.net.curl.HTTP) /usr/lib/gcc/arm-linux-gnueabihf/8/include/d/std/net/curl.d:540 0x166ab char[] std.net.curl.get!(std.net.curl.AutoProtocol, char).get(const(char)[], std.net.curl.AutoProtocol) /usr/lib/gcc/arm-linux-gnueabihf/8/include/d/std/net/curl.d:552 0x165d3 _Dmain /home/pi/builds/curldownload.d:7 0xb6abc157 ??? ???:0 0xb6abc453 ??? ???:0 0xb6abc933 ??? ???:0 0xb6abc453 ??? ???:0 0xb6abc643 _d_run_main ???:0 0x1658f main /usr/lib/gcc/arm-linux-gnueabihf/8/include/d/__entrypoint.di:44 0xb67ef717 __libc_start_main /build/glibc-FUvrFr/glibc-2.28/csu/libc-start.c:308 pi@raspi4:~/builds $ ./curldownload std.net.curl.HTTPStatusException@/usr/lib/ldc/arm-linux-gnueabihf/include/d/std/net/curl.d(1083): HTTP request returned status code 0 () ---------------- exception.d:455 pure @safe bool std.exception.enforce!(bool).enforce(bool, lazy object.Throwable) [0x24c8b] curldownload.d:1083 [0x2ccf7] curldownload.d:562 [0x1f347] curl.d:574 [0x1ee9f] curldownload.d:7 [0x1edf3] ??:? void rt.dmain2._d_run_main(int, char**, extern (C) int function(char[][])*).runAll() [0xb6ab1b17] ??:? _d_run_main [0xb6ab18af] __entrypoint.d:8 [0x32f43] ??:? __libc_start_main [0xb67dc717] ``` Compilers: gdc 8.3 ldc 1.12.0

Could reproduce this on intel too with dmd.

pi@raspi4:~/builds2 $ dpkg --status libcurl4 | grep Version Version: 7.64.0-4 Fails with both GDC and LDC2. joe@ubuntu-desktop:~/build/dlang$ dpkg --status libcurl4 | grep Version Version: 7.58.0-2ubuntu3.8 Works for all compilers. Maybe a problem with libcurl bindings? Or a bug with libcurl?

Maybe. I've got 7.64.0-4 too. (Debian stable)

I recompiled libcurl 7.64.0 from source with debug symbols enabled, and copied the result over the binary provided by raspbian. The problem is now gone. So either the Raspbian maintainers messed something up, or something else is broken.
