Looking at the traces you have sent, we see that in the working run, we have 2 successive open syscalls: run_with_page_as_heap_no.log:381:SYSCALL[25925,1](56) sys_openat ( 4294967196, 0x494d050(/system/lib64/valgrind/vgpreload_core-arm64-linux.so), 524288 ) --> [async] ... run_with_page_as_heap_no.log:412:SYSCALL[25925,1](56) sys_openat ( 4294967196, 0x494d090(/system/lib64/valgrind/vgpreload_massif-arm64-linux.so), 524288 ) --> [async] ... the failed run contains: run_with_page_as_heap_yes.log:2063:SYSCALL[25913,1](56) sys_openat ( 4294967196, 0x494d050(/system/lib64/valgrind/vgpreload_core-arm64-linux.so), 524288 ) --> [async] ... run_with_page_as_heap_yes.log:2139:SYSCALL[25913,1](56) sys_openat ( 4294967196, 0xffeffe908(/system/lib64/), 524288 ) --> [async] ... Massif uses a hack to remove vgpreload_massif-arm64-linux.so from the LD_PRELOAD, by replacing the full entry with spaces. I am guessing that on android, the dynamic linker tries to open such an 'all spaces' entry by appending it to a system lib path, causing then the open syscall to fail and cause a dynamic linking error. I have reworked the way vgpreload_massif-arm64-linux.so is removed from LD_PRELOAD, as part of revision 16306, so that the entry is really removed, rather than replaced with spaces. Can you get + compile + test the SVN version ? (see http://www.valgrind.org/downloads/repository.html to get the SVN version, README.android indicates how to build for android) Thanks Philippe ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
