Bug#764510: gcc-4.9: gnucash segfaults when built with GCC 4.9
Package: gcc-4.9
Version: 4.9.1-16
Severity: important
Control: affects -1 gnucash
[ I'm probably filing this under the wrong package/severity; please
reassign/adjust as you see fit. ]
The current version of gnucash (1:2.6.4-1) repeatably segfaults upon
launch (and entering one value), which does not happen with the previous
version (1:2.6.3-1). See the attached file for a full backtrace with
debug symbols.
After some testing, I found that the emergence of the bug does not come
from gnucash, but GCC: compiling either version with 4.8 (as was the
case with 1:2.6.3-1) works fine, while compiling with 4.9 (as was the
case with 1:2.6.4-1) triggers the bug.
I'm not quite sure how to proceed from that point on; I suppose that the
bug itself could very well be in gnucash (or glib2.0, or gtk+2.0) with
gcc/g++ 4.9 merely exposing it. Trying to bisect all four at the same
time seems like such a daunting task beyond my expertise, so any
guidance would be welcome.
