I've encountered what appears to be a Heisenbug in runtest.
Sometimes, when I run "make check", I see
--------8<--------
[ -d test ] || ln -s /afs/teragram.com/user/dgomez/prog/libxml2/test .
[ -d result ] || ln -s /afs/teragram.com/user/dgomez/prog/libxml2/result .
./runtest && ./testrecurse && ./testapi && ./testchar&& ./testdict &&
./runxmlconf
## XML regression tests
## XML regression tests on memory
## XML entity subst regression tests
## XML Namespaces regression tests
## Error cases regression tests
Error for ./test/errors/name2.xml failed
File ./test/errors/name2.xml generated an error
## Error cases stream regression tests
## Reader regression tests
## Reader entities substitution regression tests
[snip]
## C14N exclusive without comments regression tests
## C14N 1.1 without comments regression tests
## Catalog and Threads regression tests
Total 2829 tests, 1 errors, 0 leaks
make: *** [runtests] Error 1
-------->8--------
Other times, everything passes. If I invoke runtest by itself, it doesn't
even fail or succeed consistently. Valgrind turns up nothing.
I believe I've found a way for others to reproduce the issue. The attached
patch (against git master) disables all but the "Error cases regression
tests" set of tests, and with this change, I get a consistent test
failure:
--------8<--------
$ ./runtest
## Error cases regression tests
Error for ./test/errors/name2.xml failed
File ./test/errors/name2.xml generated an error
Total 11 tests, 1 errors, 0 leaks
-------->8--------
I've been unable to track down what's going on, as it occurs deep inside
the parser code and I'm not on strong footing there.
Can anyone else reproduce this, using the patch?
