I've done some debuging and it looks like a double free. Inside valgrind acroread does not crash, but outputs the following at the relevant point: Invalid free() / delete / delete[] at 0x400138F5: free (vg_replace_malloc.c:231) by 0x81FCD05: StdMemFreeProc (in /mnt/pcg/public/packages/multimedia/acroread-5.0.8/Reader/intellinux/bin/acroread) by 0x81FCEE5: ASfree (in /mnt/pcg/public/packages/multimedia/acroread-5.0.8/Reader/intellinux/bin/acroread) by 0x834BFD1: GetRidOfEncoded (in /mnt/pcg/public/packages/multimedia/acroread-5.0.8/Reader/intellinux/bin/acroread) Address 0x43B3FB94 is 0 bytes inside a block of size 7 free'd at 0x400138F5: free (vg_replace_malloc.c:231) by 0x81FCD05: StdMemFreeProc (in /mnt/pcg/public/packages/multimedia/acroread-5.0.8/Reader/intellinux/bin/acroread) by 0x81FCEE5: ASfree (in /mnt/pcg/public/packages/multimedia/acroread-5.0.8/Reader/intellinux/bin/acroread) by 0x81E783F: UnixDialogNotFoundAlert(char const *, _t_ASTextRec *, char const *) (in /mnt/pcg/public/packages/multimedia/acroread-5.0.8/Reader/intellinux/bin/acroread) So I can suggest my users running it with valgrind ;-).
