Examples of errors detected by the V590 diagnostic

V590. Possible excessive expression or typo. Consider inspecting the expression.

Stickies

V590 Consider inspecting the '* pBuff == ' ' && * pBuff != '\0'' expression. The expression is excessive or contains a misprint. stickies stickygrep.cpp 875

void ExtractHexFromEdit (....)
{
  ....
  while (*pBuff == ' ' && *pBuff != '\0')
    pBuff++;
  ....
}

Although this is not an error, this operation is unnecessary.

FCEUX

V590 Consider inspecting the 'appliedSize == 'b' && appliedSize != 's'' expression. The expression is excessive or contains a misprint. fceux ram_search.cpp 877

bool Set_RS_Val()
{

  int appliedSize = rs_type_size;
  int appliedSign = rs_t;
  if(rs_c == 'n')
    appliedSize = 'w', appliedSign = 'u';
  if(rs_c == 'a')
    appliedSize = 'd', appliedSign = 'u';
  if((appliedSize == 'b' && appliedSize == 's' &&
     (rs_param < -128 || rs_param > 127)) ||
     (appliedSize == 'b' && appliedSize != 's' &&
     (rs_param < 0 || rs_param > 255)) ||
     (appliedSize == 'w' && appliedSize == 's' &&
     (rs_param < -32768 || rs_param > 32767)) ||
     (appliedSize == 'w' && appliedSize != 's' &&
     (rs_param < 0 || rs_param > 65535)))
       return false;
  ....
}

Similar errors can be found in some other places:

• V590 Consider inspecting the 'appliedSize == 'w' && appliedSize != 's'' expression. The expression is excessive or contains a misprint. fceux ram_search.cpp 879

ReactOS

V590 Consider inspecting the '* token == ' ' && * token != '\0'' expression. The expression is excessive or contains a misprint. wininet http.c 800

static inline BOOL is_basic_auth_value( LPCWSTR pszAuthValue,
                                        LPWSTR *pszRealm )

  ....
  while (*token == ' ' && *token != '\0')
    token++;
  ....

//Enough:
while (*token == ' ')

Notepad++

V590 Consider inspecting this expression. The expression is excessive or contains a misprint. Notepad++ notepad_plus.cpp 853

int Notepad_plus::getHtmlXmlEncoding(....) const
{
  ....
  if (langT != L_XML && langT != L_HTML && langT == L_PHP)
    return -1;
  ....
}

Currently this code is equivalent to if (langT == L_PHP). The programmer probably wanted to write this code: if (langT != L_XML && langT != L_HTML && langT != L_PHP).

ICU

V590 Consider inspecting the 'secS == 0 && secS != 0x00010101' expression. The expression is excessive or contains a misprint. ucol.cpp 7893

#define UCOL_NO_MORE_CES 0x00010101

  ....

Most likely this is what should be written here: while (categoryvalue[0] != '\0' && categoryvalue[0] != ':')

The condition is long, so I'll highlight the most important part: AM == ISD::UNINDEXED || AM != ISD::POST_INC. This condition is redundant, and you can simplify it to: AM != ISD::POST_INC.
