Package: libstdc++6 Version: 4.6.0-14 Severity: normal I'm developing a piece of software and occasionally when running it I get the following:
lakeview ok % LD_LIBRARY_PATH=. test/test-mac -t hmac md5 sha1 sha256 sha512
tiger ripe160
HMAC : self-test ok (result code 0)
test/test-mac: symbol lookup error: /usr/lib/x86_64-linux-gnu/libstdc++.so.6:
undefined symbol: _ZNSt14error_categoryD2Ev, version GLIBCXX_3.4.15
lakeview no % LD_BIND_NOW=1 LD_LIBRARY_PATH=. test/test-mac -t hmac md5 sha1
sha256 sha512 tiger ripe160
HMAC : self-test ok (result code 0)
The error has no effect on the functioning of the program except for the
exit code (127 in the failed version). This only happens on certain
compiles; if I make minor changes to the code, it goes away, although
simply recompiling does not make it disappear. The problem also does
not occur if I use LD_BIND_NOW=1. I am using -Wl,--as-needed on my
compilation; the problem does not occur when I remove it. The problem
occurs with both the BFD linker and gold.
Just to be clear, the program in question is written in C and dlopens
plugins with a C interface, some of which are written in C and some of
which are written in C++. This setup works fine in other cases, but I
thought I'd mention it just in case.
