trace mode bug on next branch #37

Closed dzwduan closed 5 days ago

dzwduan commented 2 weeks ago

When i try ./runq images/bb-timing-dev on next branch with images from release latest， i get bug

CONFIG_FILE: images/bb-timing-dev
SMP: 1
f=qemu-aarch64, fd=qemu-aarch64, fn=qemu-aarch64
==348656==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.

Then i add --extra-cflags="-lasan" to build and set BUILD_TYPE -debug and run again, get error ：

==348656==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD

This indicate that libasan is not the first dynamic library within the load list. Either:

  1. Set LD_PRELOAD=[path to your libasan.so]
  2. Build both QEMU and Flexus using debug mode
dzwduan commented 2 weeks ago

Yes, I have added --extra-cflags="-lasan" to build script, it seems ok. But the new problem is SEGV on unknown address 0x000000000000 (pc 0x000000000000 bp 0x7f9326ff7e00 sp 0x7f9326ff76d8 T3)

        if [ "$BUILD_TYPE" = "debug" ]; then
            ./configure --target-list=aarch64-softmmu       \
                        --disable-docs                      \
                        --enable-savevm-external            \
                        --enable-libqflex                   \
                        --enable-debug                      \
                        --extra-cflags="-fsanitize=address" \
                        --extra-cflags="-lasan"             \
                        --extra-cflags="-fno-omit-frame-pointer"

Maybe it is because QEMU was not build using capstone, you can force it with --enable-capstone

Otherwise, I would suggest using the release mode, or disabling libasan
