[SOLVED] Segger linker merge string constants vs. strftime

Hello,

I'm currently testing the Segger linker and ran into a problem when "merge string constants" is enabled:

strftime(buffer,len,"%d-%m-%Y %H:%M:%S",datetime);

Gives the linker error:

assertion failure: section '.rodata.str.%m/%d/%y.merge' from - Linker created - is not mapped

Digging a little further (after disabling strftime()):

const char* date_format = "%m/%d/%y";

Also emits the same linker error.

const char* date_format = "%M/%d/%y";

does not.

The issue is not present when "Merge String Constants is disabled. Furthermore, it seems that "Merge String Constants" must be used with "inline small functions" linker option for the issue to be present.

I've attached a SES project that reproduces the issue. Tested with SES for ARM v4.18.

Thank you for the support! We really appreciate it. We will avoid using string merging.
