The bug seems to be in Storable.

Program received signal SIGSEGV, Segmentation fault.

Here is where Perl debugging gets ugly. "dSTCTX" expands into something or other, often through multiple layers of macros, and GDB doesn't do so well at debugging macros. Your goal is to fully expand "dSTCTX" and figure out which part of it is seg-faulting.	[reply]
