https://sourceware.org/bugzilla/show_bug.cgi?id=23646 --- Comment #4 from Cary Coutant --- Sorry, I can't reproduce the crash. I had to add -fpic to the compile command in order to link without errors. Either way, gold did not segfault. I've tried with various values for --thread-count. Can you reproduce without LTO? Can you get a stack trace from the point of the segfault? -- You are receiving this mail because: You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils

--- Comment #2 from Jean-Michaël Celerier ---
I added a source file where I removed all the code until I didn't get the
segfault anymore. The culprit (code-wise) is the last line (line 67158):
template T handle::cast() const { return
pybind11::cast(*this); }
