I'm so sorry - I left out some information and my message was not clear. Valgrind itself builds and runs fine it's the regression tests that failed to compile and/or link.
During my further investigation, the pie/no-pie linking problem turned out to be a bad file in our repository. The problem with valgrind/memcheck/tests/linux/stack_changes.c appears to be an actual problem with the source. In June of 2017 the gnu c header file sys/ucontext.h was changed. typedef struct ucontext is now typedef struct ucontext_t. This change is included in the latest release of glibc 2.26 (Aug 2017).

And is it a problem in building valgrind itself, or in applying an old valgrind to newly-compiled code? Please give an explicit example (copy+paste) of a new complaint, and analyze it as best you can. -- ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
