New issue 386 by [email protected]: JNI-based app fails with shadow memory
range interleaves with existing memory mapping after ASan instrumentation
https://code.google.com/p/address-sanitizer/issues/detail?id=386
What steps will reproduce the problem?
1. Build JNI C++ code with -fsanitize=address flag turned on against
jdk-7u10-64.
2. Build Java code which uses the JNI interface against jdk-7u10-64.
3. Run the generated jar above.
What is the expected output? What do you see instead?
I expect the program to run. Instead the program crashes with the following
error:
==4402== Shadow memory range interleaves with an existing memory mapping.
ASan cannot proceed correctly. ABORTING.
==4402== Process memory map follows:
0x000000400000-0x000000401000 /usr/local/jdk-7u10-64/bin/java
0x000000600000-0x000000601000 /usr/local/jdk-7u10-64/bin/java

0x7f5758951000-0x7f5758a4f000 [stack:6043]
0x7f5758a4f000-0x7f5758a52000
...
What version of the product are you using? On what operating system?
GCC version: gcc-4.8.1-glibc-2.17
JDK version: jdk-7u10-64
Please provide any additional information below.
I have a question. Is there a way to re-configure the reserved base
addresses for ASan so that they don't interleave with existing memory
mapping from JVM?
Any help would be highly appreciated!
