Ok; no wonder I couldn't find any DeleteLocalRef problems. > In my experience, crashes during GC are often the result of something > scribbling on the virtual heap.

With forcecopy enabled, I now get the crash in a different location: I/DEBUG ( 547): Build fingerprint: 'generic/sdk/generic/:1.5/ CUPCAKE/148875:eng/test-keys' I/DEBUG ( 547): pid: 713, tid: 738 >>> com.flexilis <<< I/DEBUG ( 547): signal 11 (SIGSEGV), fault addr 00000002 I/DEBUG ( 547): r0 00000002 r1 afe3cd28 r2 00000002 r3 00000002 I/DEBUG ( 547): r4 afe3cd28 r5 00194c2c r6 8044f2d4 r7 00000078 I/DEBUG ( 547): r8 45d28cb8 r9 afe39dd0 10 8044f2d4 fp 46628e6c I/DEBUG ( 547): ip 804d13c4 sp 46628e18 lr afe1355d pc afe0e14c cpsr 00000010 I/DEBUG ( 547): #00 pc 0000e14c /system/lib/libc.so I/DEBUG ( 547): #01 pc 0001355a /system/lib/libc.so Which corresponds to the strlen() call within fputs(), but which unfortunately doesn't clarify the situation at all, since we don't have any calls to fputs(). We also don't have any calls to fwrite() or fprint() nearby that might be using fputs(). I can't prove this is the same crash as the other one, but since I haven't seen any other crashes recently I think it's the same bug. Unfortunately the bug is not easily reproducible so I can't build a simple testcase.
