After doing `apt-get source sqlite3` and building it myself with `debuild -b -us -uc`, I have the source file `sqlite3.c` and I am able to look at the code statements. > The backtrace from the core dump file is the following. > > Thread 1 (Thread 0x8acf1b70 (LWP 15522)): > #0 0xb69bafe3 in pcache1Fetch (p=0xb8effb00, iKey=35985, > createFlag=2) at sqlite3.c:36093 > h = 1169 > nPinned = <optimized out> > pCache = 0xb8effb00 > pGroup = 0xb8effb30 > pPage = 0xbf8ab0e8 The following code caused the segmentation fault. 36093 *(void **)pPage->page.pExtra = 0; (gdb) l 36088 pPage->iKey = iKey; 36089 pPage->pNext = pCache->apHash[h]; 36090 pPage->pCache = pCache; 36091 pPage->pLruPrev = 0; 36092 pPage->pLruNext = 0; 36093 *(void **)pPage->page.pExtra = 0; 36094 pCache->apHash[h] = pPage; 36095 } 36096 36097 fetch_out: (gdb) p pPage $1 = (PgHdr1 *) 0xbf8ab0e8 (gdb) p pPage->page.pExtra $2 = (void *) 0x5 (gdb) info register eax 0x5 5 ecx 0xb8effb30 -1192232144 edx 0x491 1169 ebx 0xb6a51d3c -1230693060 esp 0x8acf0850 0x8acf0850 ebp 0xb8effb00 0xb8effb00 esi 0xbf8ab0e8 -1081429784 edi 0xb8effb00 -1192232192 eip 0xb69bafe3 0xb69bafe3 <pcache1Fetch+755> eflags 0x10212 [ AF IF RF ] cs 0x73 115 ss 0x7b 123 ds 0x7b 123 es 0x7b 123 fs 0x0 0 gs 0x33 51 As *(void **)pPage->page.pExtra = 0; is above my basic C knowledge, maybe somebody sees if there is a reason for the segfault here. Otherwise Richard is probably right, that the heap corruption is caused by some other program. Thanks, Paul
