Bug: assert( p->iForeGuard==(int)FOREGUARD );

[stannko]

I'm getting an assertion failed error while running my application that utilizes the latest published version of the library. I cannot determine the exact scenario of getting this error. It looks like it happens randomly time to time while reading from the database. I encountered this issue on arm and x64 devices as well.

My investigation leads to a file:
https://github.com/mbrit/sqlite-metrostyle/blob/master/FromSqliteOrg/tsrc/mem2.c

sqlite3MemsysGetHeader
Line: 159

I attach a screenshot.

Same problem here. Any resolution?

Same error for me.... Does anyone find the solution? Even for me it happens randomly.
The comment of this method in the source code says:
/*
** Given an allocation, find the MemBlockHdr for that allocation.
**
** This routine checks the guards at either end of the allocation and
** if they are incorrect it asserts.
*/

but what's the checks of the guards?
