Hello everyone,
I am new to the list. I am working on an application in which I will be
embedding SQLite as the database engine. The application is written in
C.
I am currently having an issue which I am not able to resolve at the
moment so I thought I would ask here since I am just starting out with
SQLite.
My problem is, from my point of view, that I am not able to perform an
action to the same database file in the following manner:
1) I open a database via:
sqlite3_initialize()
sqlite3_open_v2
2) I do some work on getting metadata from the database like table
names and their fields and then
3) I close the connection via:
sqlite3_close_v2
sqlite3_shutdown
4) After all of this is done I wish to process an import file so I need
to open another connection to the same database file and run some
statements but when I try to do that I get this on the open call in
step 1 (above):
malloc.c:2372: sysmalloc: Assertion `(old_top == (((mbinptr) (((char *)
&((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct
malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size)
>= (unsigned long)((((__builtin_offsetof (struct malloc_chunk,
>fd_nextsize))+((2 *(sizeof(size_t)) < __alignof__ (long double) ?
>__alignof__ (long double) : 2 *(sizeof(size_t))) - 1)) & ~((2
>*(sizeof(size_t)) < __alignof__ (long double) ? __alignof__ (long
>double) : 2 *(sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) &&
>((unsigned long) old_end & pagemask) == 0)' failed. Aborted (core
>dumped)
This happens in on line 17149 when calling:
p = SQLITE_MALLOC( nByte+8 )
nByte is 64000
in sqlite3.c (amalgamation latest version
sqlite-amalgamation-3081002.zip)
I am compiling and running the code on:
Linux x140e 3.13.0-53-generic #89-Ubuntu SMP Wed May 20 10:34:28 UTC

Any suggestions or directions greatly appreciated.
