[Valgrind-users] ARM Thumb unimplemented instruction

2011-11-24 Thread Alexander Graf
Hi list, While trying to debug some gcc breakage, I stumbled over an unimplemented opcode in 3.7.0: ==30077== Command: /usr/lib/gcc/armv7l-suse-linux-gnueabi/4.6/../../../../armv7l-suse-linux-gnueabi/bin/as -march=armv7-a -mfloat-abi=hard -mfpu=vfpv3-d16 -meabi=5 -o /tmp/ccP7oOkQ.o /tmp/ccX6Y

Dear valgrind developper, I'm currently trying to use this software to try to fix a memory leak. I try to run a macro that runs fine if I excecute WITHOUT using valgrind. When I excecute it using valgrind it crashes. The complete thread: ( I try to compile and load a class called AppleDrillAngle

Hi masters of the memory problems... I have an annoying problem, where I need some general hints. An you might know already I have been using valgrind (mostly memtool) for a long time - so the basics are ok. My current Linux-program give one valgrind error - at random - every ~0.01% of th
