Bug ID: 33206
Summary: Sanitizer CHECK failed: ((allocated_for_dlsym)) <
((kDlsymAllocPoolSize)) (1036, 1024)) with preload

patch for this Issue
Hello everyone,
I've faced a situation with error:
Sanitizer CHECK failed: asan_malloc_linux.cc:42 ((allocated_for_dlsym)) <
((kDlsymAllocPoolSize)) (1036, 1024).
when LD_PRELOAD set to libclang_rt.asan-x86_64.so
It seems like there is might be a situation when asan initializing later than
shared library which has malloc in static constructor. (rtld doesn't provide
the order of initiazation). In this case asan doesn't init interceptors but
already intercepting malloc (for example). If malloc is too big to be handled
by static local pool asan will die with error:
Sanitizer CHECK failed: libsanitizer/asan/asan_malloc_linux.cc:40
((allocated_for_dlsym)) < ((kDlsymAllocPoolSize)) (1036, 1024)
I have a patch which can help to resolve this problem.
Can someone please review that patch.
Thanks.
