c++11 - boost::multi_index_container erase function rehases? -

-

I have the following problem: I have a promotion: :: mult_index_container, here is a simplified definition of the TYPE an integral type 

  boost :: multi_index:  a member function indicator  and type: m_id  by  m_id : multi_index_container & lt; TYPE *, Promotion: Multi_Index :: Index_Bine & lt; :: multi_index :: hashed_unique promote & lt; Boost :: multi_index :: tag & lt; By_hashed_id & gt;, boost :: mult_index :: member & lt; Type, const type, and type :: m_id & gt; & Gt; & Gt; & Gt; Map;

When I delete an object in the following way: 

  hashmap = map.index.get & quot; By_hashed_id & gt; () This = hishmap.fid (30); Erase it; /// Remove the underlying pointer hashmap.rase (this); Erase the /// map (the map is shown again (segfault) ()?

are trying to touch it again the code seems to crash whenever Map , what no one knows is that this is normal behavior, it can be reborn a delete function before removing indicators, which will result in a Segfolt results because the indicator has already been deleted (Definitely it is decided that delete erase which is anyway more suitable!)

I found the following trace after the segmentation fault.

last stack trace output: 

  [a9203: 03910] signal: segmentation fault (11) 121 [a9203: 03910] Signal code: address not mapped (1 ) 122 [a9203: 03910] addresses denied on: (null) 123 [a9203: 03910] [0] /lib64/libc.so.6 () [0x36846329a0] 124 [a9203: 03,910] [1] / lib64 / libc. so.6 () [0x368468e312] 125 [a9203: 03,910] [2] / program (ZNSt10_HashtableIjSt4pairIKjN15BodyProcessInfo5FlagsEESaIS4_ENSt8__detail10_Select1stESt8equal_toIjESt4hashIjENS6_18_Mod _range_h AshingENS6_20_Default_ranged_hashENS6_20_Prime_rehash_policyENS6_17_Hashtable_traitsILb0ELb0ELb1EEEE5clearEv + 0x3F)

To answer the question in your subject line: Directed Index , As you use in the code shown, it is not like H / Rehash ever because they are not based on the hedged index (which appears to be you are not used here) delete But do not start over again. The symbol shown on stack traces looks completely foreign for Boost. Multi Indexes

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
