https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: dev-libs/libzia-4.37 leaves trace of segfault in dmesg. Discovered on: amd64 (internal ref: ci) NOTE: To reproduce this issue: 1) Install the package with FEATURES=test 2) Check dmesg output with: dmesg -T | grep -E '( segfault | traps:| audit:)' This type of report comes from a check that is a bit outside of the tinderbox, that's the reason because build.log was not provided (however in cases like these the build.log doesn't help much) but if you need further help to diagnose this issue feel free to ask. In any case I'm providing what I can see via dmesg.
[Tue Oct 25 09:41:25 2022] conftest[2190]: segfault at e9ca854 ip 00007f610e991a79 sp 00007fffbfaf81b8 error 4 in libc.so.6[7f610e85e000+150000] [Tue Oct 25 09:44:03 2022] conftest[25190]: segfault at 7f0f6854 ip 00007fc77f0bda79 sp 00007ffe3c9def08 error 4 in libc.so.6[7fc77ef8a000+150000]
According to configure.log the following snippet from configure.ac seemst o be the reason for the segfault: -- #include <features.h> #include <stdio.h> #ifdef __CYGWIN__ #include <cygwin/version.h> #endif FILE *f; int main(void){ f=fopen("conftest.libc.out", "wt"); if (!f) return -1; #ifdef __GLIBC__ fprintf(f, "glibc %d.%d (%s)\n", __GLIBC__, __GLIBC_MINOR__, gnu_get_libc_version()); #endif #ifdef __CYGWIN__ fprintf(f, "cygwin %d.%d.%d, api %d.%d\n", CYGWIN_VERSION_DLL_MAJOR/1000, CYGWIN_VERSION_DLL_MAJOR%1000, CYGWIN_VERSION_DLL_MINOR, CYGWIN_VERSION_API_MAJOR, CYGWIN_VERSION_API_MINOR); #endif fclose(f); return 0; } -- Compiler complains about missing prototype of gnu_get_libc_version() and assumes return type 'int' but the printf() expects an 'char *' instead. Sounds like a missing include file.
(In reply to Thomas Beierlein from comment #2) > Compiler complains about missing prototype of gnu_get_libc_version() and > assumes return type 'int' but the printf() expects an 'char *' instead. > Sounds like a missing include file. Adding '#include <gnu/libc-version.h>' does indeed fix the problem. Downside is that the function 'gnu_get_libc_version' seems not to exist in MUSL libc. So using the above include does not solve the problem for musl profiles. Needs more work
