But your remark had me check the line above once more...which made me more suspicious and I replaced (my) version of the libc by the system one (with which valgrind had been compiled). And VOILA: Problem solved. All messages of valgrind make completely sense now, whereas they looked absolutely chinese to be before. Probably the mismatch of C-libraries threw valgrind under the bus. Interesting to see that valgrind nevertheless was able to produce messages (which, however, did not make sene to me). Would be nice if valgrind could detect/warn about that. THANK YOU very much for you help, it saved my day - I ws really a bit desperate already. > You can also try "gdb <my_program>" and then "x/10i 0x6E6E2CA" to see > what the faulting instruction actually is.

Didn't know this trick and it probably will save my weekend - since I *am* actually using some SSE-related code fragments which still are awaiting valgrind-cleanup later today :-) THANX. -- View this message in context: http://valgrind.10908.n7.nabble.com/DESPERATE-Receiving-confusing-warnings-during-very-short-execution-phase-tp46345p46352.html Sent from the Valgrind - Users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
