But i have met an issue below when building images: ```log EROFS: write_uncompressed_block() Line[140] Writing 3517 uncompressed data to block 63950 EROFS: erofs_mkfs_build_tree() Line[1011] add file /tmp/merge_target_files_jnIVhM/output/VENDOR/etc/xtwifi.conf (nid 8185600, type 1) EROFS: erofs_mkfs_build_tree() Line[1011] add file /tmp/merge_target_files_jnIVhM/output/VENDOR/etc (nid 1790208, type 2) out/host/linux-x86/bin/mkerofsimage.sh: line 79: 188014 Segmentation fault (core dumped) $MAKE_EROFS_CMD ``` Have you met this kind of issue? I'm trying to debug the problem, looks like memory related. BTW: i'm using latest erofs-utils in AOSP master branch (https://android.googlesource.com/platform/external/erofs-utils/). Thx. ^ permalink raw reply [flat|nested] 6+ messages in thread

Which lz4 version is used? it would be better to use lz4 1.9.3 (or 1.9.2 with some unexpected CR issues.) For more details, please see README. If the expected lz4 version is used, could you kindly leave gdb backtrace message here as well? Thanks, Gao Xiang > > Thx. > ^ permalink raw reply [flat|nested] 6+ messages in thread

At least, lz4 1.8.3 ~ 1.9.1 are buggy, for more details, see: https://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs-utils.git/tree/README?h=dev#n107 > > > For more details, please see README. > > > > If the expected lz4 version is used, could you kindly leave gdb > > backtrace message here as well? > > Trying to get the bt for the case. Yeah, bt will fall into lz4 internal functions if the lz4 version is too low.
