--- Begin Message ---Source: pdns-recursor Version: 4.1.0-1 Severity: serious Tags: sid buster patch Hi, pdns-recursor FTBFS on mips64el due segfaulting (or another crash) while executing the mtasker tests. Build log (exit status 139 = SIGSEGV): > Checking bad value for record type SOA test #1 > FAIL testrunner (exit status: 139) Similar errors occur on other architectures which might be related to the failure on mips64el, but I did not investigate those. On mips64el the crash comes as a result of throwing an exception in the willThrow function in test-mtasker.cc. Throwing an exception makes a call into the stack unwinder in libgcc which uses enough stack space to overflow the stack allocated for the currently running task. In this case, it just so happens that the return ucontext gets overwritten by the stack overflow and after returning from threadWrapper, we jump to some garbage memory location. The attached patch fixes this by increasing the stack size for all 128k for all tasks. The 32-bit build failures are related to #887030. Thanks, James--- a/mtasker.hh +++ b/mtasker.hh @@ -110,7 +110,7 @@ public: This limit applies solely to the stack, the heap is not limited in any way.
