Since you mention the default is 64MB on Linux and it says\n\"Increase stack limit to a figure based on the Linux default,with 4MB\nadded\".\nI am thinking we should change the comment to mention 16MB and the\ndefault on Linux at the time of commit was 64MB.\n\nOk for trunk and 15 branch, with the comment updated in both files.\n\nThanks,\nAndrew\n\n\n>\n> Ok for trunk and releases/gcc-15?\n>\n> Kind regards,\n> Torbjörn\n>\n> --\n>\n> This fixes fails like below on Windows.\n>\n> FAIL: gcc.c-torture/compile/limits-exprparen.c -O0 (test for excess errors)\n>\n> On Linux, maybe also other targets, the stack limit is dynamically\n> changed when the application launches.\n>\n> config/ChangeLog:\n>\n> * mh-cygwin: Increase to 16MB stack reserve.\n> * mh-mingw: Likewise.\n>\n> Signed-off-by: Torbjörn SVENSSON \n> ---\n> config/mh-cygwin | 4 ++--\n> config/mh-mingw | 4 ++--\n> 2 files changed, 4 insertions(+), 4 deletions(-)\n>\n> diff --git a/config/mh-cygwin b/config/mh-cygwin\n> index 1f746bdea84..3be1cfe5dc3 100644\n> --- a/config/mh-cygwin\n> +++ b/config/mh-cygwin\n> @@ -1,4 +1,4 @@\n> # Increase stack limit to a figure based on the Linux default, with 4MB added\n> # as GCC turns out to need that much more to pass all the limits-* tests.\n> -LDFLAGS += -Wl,--stack,12582912\n> -BOOT_LDFLAGS += -Wl,--stack,12582912\n> +LDFLAGS += -Wl,--stack,167772160\n> +BOOT_LDFLAGS += -Wl,--stack,167772160\n> diff --git a/config/mh-mingw b/config/mh-mingw\n> index f5fb064813f..787719a06c8 100644\n> --- a/config/mh-mingw\n> +++ b/config/mh-mingw\n> @@ -10,5 +10,5 @@ STAGE4_CXXFLAGS += -D__USE_MINGW_ACCESS\n>\n> # Increase stack limit to a figure based on the Linux default, with 4MB added\n> # as GCC turns out to need that much more to pass all the limits-* tests.\n> -LDFLAGS += -Wl,--stack,12582912\n> -BOOT_LDFLAGS += -Wl,--stack,12582912\n> +LDFLAGS += -Wl,--stack,167772160\n> +BOOT_LDFLAGS += -Wl,--stack,167772160\n> --\n> 2.43.0\n>","headers":{"Return-Path":"","X-Original-To":["incoming@patchwork.ozlabs.org","gcc-patches@gcc.gnu.org"],"Delivered-To":["patchwork-incoming@legolas.ozlabs.org","gcc-patches@gcc.gnu.org"],"Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (2048-bit key;\n unprotected) header.d=qualcomm.com header.i=@qualcomm.com header.a=rsa-sha256\n header.s=qcppdkim1 header.b=lPkZfD7B;\n\tdkim=pass (2048-bit key;\n unprotected) header.d=oss.qualcomm.com header.i=@oss.qualcomm.com\n header.a=rsa-sha256 header.s=google header.b=HOsvnP9B;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=gcc.gnu.org\n (client-ip=38.145.34.32;
