That is a stack trace, after the SIGSEGV (Signal, Segment Violation) message, below where is says "stack:". Do an 'objdump -x' on the .so (/ system/lib/egl/ libGLES_qcom.so), and start matching up the addresses with code. It should lead you to the specific routine that the code crashed in. The first few lines after SIGSEGV are a register dump, so you can tell what was happening when the crash occurred. Looks like "r2" (Register 2) was the one that was used in the reference that violated memory protection. You can disassemble the code around the routine at the top of the stack, near the address of the fault, and find the code that did it. You can add options to the compile of the .so to produce assembly source code that retains the associated C code in comments. Once you're up into the C code, you can probably pretty well determine what went wrong. Perhaps an out-of-bounds value was passed into an OpenGL function. Perhaps more memory was needed in a buffer that had little, and OpenGL ran off the end.
I think there may even be scripts out there which will take the binary addresses shown in this stack dump and will find names for the routines, by automating part of what I described above. Also, if you can park the application, attach strace to it, and then unpark it and cause it to produce the bug, the strace output will show a chronological trace of the system calls that led up to the crash.
