`pass_clang_binsrch.pm` fails with `Use of uninitialized value $line`

[jketema]

When running creduce on some particular large C++ file. I see the following errors:

===< pass_clang_binsrch :: replace-function-def-with-decl >===
Use of uninitialized value $line in pattern match (m//) at c:/.../pass_clang_binsrch.pm line 36.
===< pass_clang_binsrch :: remove-unused-function >===
Use of uninitialized value $line in pattern match (m//) at c:/.../pass_clang_binsrch.pm line 36.

Is there some way for me to diagnose why this is happening?

Hmm. How large is the input file?

My uninformed guess is that something is running out of memory—how else would $line be uninit'ed at that point?

[jketema]

Hmm. How large is the input file?

About 25MB.

It might indeed be a size problem, once pass_lines :: 0 had reduced the file to about 15MB and I restarted creduce, I no longer got the error.
