Hi all,
We are consistently getting segfaults with core dumped from freeview.bin when trying to open MGZ files that are larger than some (undetermined) threshold.
We are running the 4.5.0 CentOS 4 x86_64 binary package on Ubuntu 9.04 Workstation. Upon opening freeview and attempting to load one of the larger files, the application crashes and dumps core, and leaves the following in the error.log:
CTABreadASCII(/u2/meeshy/Desktop/Amy Activation Screenshots/SAD_022/lh_Novelobjects_social/EFvNF.png): badly formed file mghRead: encountered error executing: 'zcat /u2/meeshy/Desktop/I29/flash20_100um_avg_rotatedKH11112009_mfg_new.mgz',frame -1, errno 12 mghRead: encountered error executing: 'zcat /u2/meeshy/Desktop/I29/flash20_100um_avg_rotatedKH11112009_mfg_new.mgz',frame -1, errno 12
(running that same zcat command from the command line works fine)
Loading the resulting core into gdb:
meeshy@ba7:~$ gdb `which freeview.bin` ./core [mumble mumble reading symbols] ... Core was generated by `freeview.bin'. Program terminated with signal 11, Segmentation fault.

These are around 250MB in size. Smaller files load just fine.
