Hi ,
I am running libc-testsuite linking it statically with musl libraries
Here is my gcc version:
gcc -v
Using built-in specs.
Target: x86_64-redhat-linux
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man
--infodir=/usr/share/info --enable-shared --enable-threads=posix
--enable-checking=release --with-system-zlib --enable-__cxa_atexit
--disable-libunwind-exceptions --enable-libgcj-multifile
--enable-languages=c,c++,objc,obj-c++,java,fortran,ada
--enable-java-awt=gtk --disable-dssi --enable-plugin
--with-java-home=/usr/lib/jvm/java-1.4.2-gcj-1.4.2.0/jre --with-cpu=generic
--host=x86_64-redhat-linux
Thread model: posix
gcc version 4.1.2 20080704 (Red Hat 4.1.2-44)
I noticed that setjmp test constantly fails for me with the following error
message:
setjmp.c:51: sigismember(&set, 10)==0 failed: siglongjmp failed to restore
mask
setjmp test failed, 1 error(s)
However if I comment out all the rest functions calls from testsuite.c file
, setjmp alone surprisingly passes as if its failure is somehow connected
to other tests. Specifically memstream is the one that affects
success/failure of setjmp.
Please see attached output of strace -v -s 512 -F -f -o out_fail.txt
./testsuite ( a failing case when only memstream and setjmp are present
in testsuite.c file ) and strace -v -s 512 -F -f -o out.txt ./testsuite ( a
success case when only setjmp is present in testsuite.c file).
Any ideas why the failure happens ?
Thanks,
Tim.

I just committed a fix; let me know if your problem persists. I also
committed an improvement to the testsuite, which you might want to try
first, which should reliably detect the error you found in musl.
Thanks!

Hi,
With the latest versions of musl and libc-testsuite the problem
disappeared.
Thanks,
Tim.
