Subject: [PATCH] Avoid .symver on common symbols [BZ #21666] |
54 |
|
55 |
The .symver directive on common symbol just creates a new common symbol, |
56 |
not an alias and the newer assembler with the bug fix for |

will issue an error. Before the fix, we got |
61 |
|
62 |

in libc.so. The versioned loc1, loc2 and locs have the wrong addresses. |

After the fix, we got |
